What does heat absorption mean what does heat release mean?

absorbing heat without increase in temperature when heated beyond a certain point. Antonyms: exothermal, exothermic, heat-releasing. (of a chemical reaction or compound) occurring or formed with the liberation of heat. energy-releasing, exoergic.

What is the difference in the rate of absorbing and releasing of heat by the land and bodies of water?

Land surfaces absorb much more solar radiation than water. This is due to the fact that most land surfaces are darker than water which of course means more absorption of solar radiation and heat. Water reflects most solar radiation that reaches its surface back to the atmosphere.

How will you explain the effect of the absorption and release of heat?

When absorbed by a substance, heat causes inter-particle bonds to weaken and break which leads to a change of state (solid to liquid for example). There is no increase in the particle motion and hence no rise in temperature. THERMAL ENERGY is one type of INTERNAL ENERGY possessed by an object.

How do you calculate heat absorbed or released?

To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in …

Which has the better ability to absorb energy or heat and retain the heat?

Water is able to absorb heat – without increasing much in temperature – better than many substances. Heat capacity is the capability of water to absorb heat without undergoing an increase in temperature.

Why there is difference in heating of land and water?

It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth. Different energy transfer processes also contribute to different rates of heating between land and water.

Does evaporation absorb or release heat?

In the case of evaporation, the energy is absorbed by the substance, whereas in condensation heat is released by the substance.

What process absorbs heat?

An endothermic process absorbs heat and cools the surroundings.”
