A clinical thermometer cannot be used for boiling water or ice, as it typically measures temperatures between 35°C and 42°C. Boiling water exceeds this range, and ice is below it, potentially damaging the thermometer.
Before thermometers, fever was detected through physical signs like feeling unusually warm or hot to touch, and by observing symptoms such as sweating, shivering, or changes in skin color and behavior.
To measure temperatures beyond the range of a clinical thermometer, use specialized thermometers such as digital thermometers, infrared thermometers, or laboratory thermometers designed for higher or lower temperature ranges, depending on the measurement needs.
Natural grass feels cooler than plastic grass because it undergoes evaporation, which absorbs heat and cools the air. Plastic grass, however, does not evaporate and absorbs and retains more heat, making the surrounding area warmer.
Water interacts with materials through processes like dissolution, adsorption, and capillary action. It can dissolve substances, adhere to surfaces, and move through porous materials, affecting various physical and chemical properties of those materials.
Water impacts human health by supporting essential bodily functions, such as digestion and temperature regulation. Contaminated water can lead to diseases, while access to clean water is crucial for maintaining overall health and well-being.
Ice affects sea levels by storing water in solid form. Melting ice, especially from glaciers and polar ice caps, contributes to rising sea levels, which can lead to coastal flooding and habitat loss.
Water contributes to soil erosion by washing away topsoil through rainfall and runoff. The force of moving water dislodges and transports soil particles, leading to loss of fertile land and impacting agricultural productivity.
Ocean currents influence climate by redistributing heat across the globe. Warm currents can raise temperatures in coastal regions, while cold currents can cool them. These currents affect weather patterns and climate zones.
