In which case does light undergo the greater change in speed—traveling in air and entering a glass lens, or traveling in water and entering a glass lens?
To state: The term used to describe the energy required to raise the temperature of 1kg of a material by 1°C.
Explanation of Solution
Introduction:
Every substance absorbs different amount of thermal energy from the heat source which depends upon its own individual properties. Due to the absorption of this thermal energy, its temperature changes which depends upon the nature of the substance.
The specific heat of a material is the amount of heat energy required to raise the temperature of 1 kg of a material by 1°C. It is measured in joules per kilogram degree Celsius (
Conclusion:
The energy required to raise the temperature of 1 kg of a material by 1°C is a material’s specific heat.
