Answer:
The colder object will warm up and hotter object will cool down.
Explanation:
The transfer of thermal energy from a system to its surroundings is called heat.
It is also the transfer of thermal energy from one object to another because of the difference in temperature.
The unit of heat is joules (J). This is happen because heat is a transfer of energy.
The measure of how hot or cold a substance feels is called temperature. Temperature is measured in degree Celsius (°C) .
The average kinetic energy of the particles in an object or system is called Temperature.
To measure the temperature of an object or substance we use thermometer.
The transfer of energy is called heat.
The energy moves from the hotter object to the colder object due to transfer of energy.
So the colder object will warm up and hotter object will cool down.
