Answer:
What happens when carbon dioxide at 74°C is placed in thermal contact with water at 14°C? Energy leaves the carbon dioxide and enters the water. The water gets hotter than the carbon dioxide. The temperatures of the two substances equalize. Both the water and the carbon dioxide decrease in temperature. The water stays colder than the carbon dioxide.
Explanation:
The temperatures of the two substances equalize when carbon dioxide at 74°C is placed in thermal contact with water at 14°C.
A state in which two or more systems can exchange thermal energy.
As two objects at different temperatures are placed in contact, heat is transferred from the warmer to the cooler object until the temperature of the two objects is the same.
The amount of heat that is transferred from the warmer object is equal to the amount of heat that is transferred into the cooler object.
This is in agreement with the law of conservation of energy.
Hence, the temperatures of the two substances equalize.
