When the kinetic energy of a solid increases, typically due to heating, the particles within the solid begin to move more quickly and vibrate more intensely. This increased movement disrupts the orderly arrangement of particles in the solid’s structure. As the temperature continues to rise, the particles gain enough energy to overcome the forces holding them in fixed positions.
As the intermolecular forces weaken, the solid starts to lose its rigidity, allowing the particles to move more freely. Once the kinetic energy reaches a certain level, the particles break free from their fixed positions, and the solid begins to melt. This transition from solid to liquid state occurs at the melting point, where the increased kinetic energy enables the particles to flow past one another, leading to the melting of the solid.
When the temperature of a solid is increased, the kinetic energy of its particles also increases. This rise in kinetic energy causes the particles to vibrate more rapidly and with greater intensity around their fixed positions. As the kinetic energy continues to increase with temperature, the particRead more
When the temperature of a solid is increased, the kinetic energy of its particles also increases. This rise in kinetic energy causes the particles to vibrate more rapidly and with greater intensity around their fixed positions. As the kinetic energy continues to increase with temperature, the particles exert greater forces against each other, and their motions become more pronounced.
The solid’s structure can become less stable as the particles’ vibrations disrupt the orderly arrangement. If the temperature increase is sufficient to reach the solid’s melting point, the kinetic energy of the particles will allow them to overcome intermolecular forces and move more freely. This process leads to the solid transitioning into a liquid state. Overall, increasing temperature in a solid raises the kinetic energy of its particles, affecting their movement and potentially causing a phase change.

Increasing the temperature of a gas increases its pressure because of the relationship between temperature, kinetic energy, and the motion of gas particles. When the temperature of a gas rises, the kinetic energy of its particles also increases. As a result, the gas particles move faster and collide with the walls of their container more frequently and with greater force.
The increased frequency and intensity of these collisions generate higher pressure inside the container. According to the ideal gas law (PV = nRT), an increase in temperature (T) at constant volume (V) and a fixed amount of gas (n) leads to an increase in pressure (P). Therefore, higher temperatures result in higher gas pressure due to the increased kinetic energy and speed of the gas particles, causing them to exert more force on their container’s walls.

Most of the total body weight of an animal consists of (a) Water. Water is a fundamental component of living organisms, constituting a substantial proportion of an animal’s body mass. It serves essential roles in biological processes, including hydration, nutrient transport, waste removal, and temperature regulation. Water forms the basis of bodily fluids, such as blood, lymph, and digestive juices, facilitating various physiological functions. While blood, bone, and tissues are crucial components of an animal’s body composition, they collectively make up a smaller proportion compared to water. Blood primarily consists of plasma and cells, bone provides structural support and mineral storage, and tissues comprise cells organized into specialized structures performing specific functions. However, water surpasses them all in terms of sheer volume, making it the predominant constituent of an animal’s body weight and indispensable for sustaining life and metabolic activities.

Gases enter and leave the blood during respiration primarily by (c) Diffusion and active circulation. Diffusion allows for the passive movement of gases like oxygen and carbon dioxide across the thin membranes of the alveoli in the lungs and the capillaries surrounding them. Meanwhile, active circulation, driven by the pumping action of the heart, facilitates the transport of oxygen-rich blood from the lungs to the body tissues and the return of carbon dioxide-rich blood from the tissues back to the lungs for exchange, ensuring a continuous supply of oxygen and removal of carbon dioxide.

The number of essential amino acids in the human body is (b) 20. These amino acids are crucial for various physiological processes, including protein synthesis, enzyme function, and tissue repair. They cannot be synthesized by the body and must be obtained through dietary sources. Essential amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, along with arginine (essential in children), and the semi-essential amino acids cysteine, tyrosine, glycine, proline, serine, asparagine, glutamine, and alanine. Ensuring an adequate intake of these amino acids is essential for maintaining optimal health and well-being.

The metal present in myoglobin is (d) Iron. Myoglobin is a protein primarily found in muscle tissues, particularly in skeletal and cardiac muscles. It plays a crucial role in oxygen storage and transport within muscle cells. Each myoglobin molecule contains a single iron ion (Fe2+) at its core, which binds reversibly to oxygen molecules, facilitating their storage and release as needed during muscle contraction and metabolic activities. This iron ion is essential for the protein’s function, enabling it to efficiently capture oxygen from the bloodstream when oxygen levels are high and release it when oxygen demand increases during muscle activity. Without this iron ion, myoglobin would not be able to perform its vital role in supplying oxygen to muscle tissues, which is essential for energy production and overall muscle function.

Prothrombin is related to (b) Blood coagulation. It is a vital component in the process of clot formation, known as hemostasis. When blood vessels are injured, prothrombin is converted into thrombin through a series of enzymatic reactions, leading to the formation of a fibrin clot. This clotting mechanism helps to prevent excessive bleeding by sealing off damaged blood vessels. Without prothrombin and the subsequent clotting process, individuals would be at risk of hemorrhage even from minor injuries, highlighting the critical role of prothrombin in maintaining vascular integrity and overall hemostasis.

The function not associated with the human kidney is (b) Control of sugar level in blood. While the kidneys play essential roles in regulating water balance, filtering waste products like urea, and secreting various hormones involved in blood pressure regulation and red blood cell production, they are not directly involved in controlling blood sugar levels. This function primarily falls under the purview of the pancreas, which secretes hormones such as insulin and glucagon to regulate glucose metabolism. Therefore, while the kidney performs numerous vital functions, controlling blood sugar levels is not among its primary responsibilities.
