The reason for the temperature of water at the bottom of the waterfall being higher is – The kinetic energy of falling water is converted into heat. As water falls, its kinetic energy transforms into thermal energy due to friction ...
Camels feel relief from the desert heat by increasing their body temperature to 42°C. This allows them to conserve water by reducing sweating and water loss. Camels also have adaptations like fat storage in humps, long legs, and thick fur ...
By increasing the pressure on ice, its melting point will increase. Pressure affects the equilibrium between solid and liquid phases. As pressure rises, the equilibrium shifts towards the more compact solid phase, requiring a higher temperature to maintain equilibrium, resulting ...
Gas thermometers are more sensitive than liquid thermometers because gases has higher coefficient of expansion. Gas molecules expand more readily in response to temperature changes compared to liquids, leading to more significant changes in volume for a given temperature change. ...
