Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you heat equal masses of water and metal with the same amount of heat,
A
the water will get hotter faster
B
the metal will get hotter faster
C
the metal will get hotter slower
D
they heat up at the same rate
Explanation: 

Detailed explanation-1: -Water has a higher specific heat, so it takes more energy to warm the same amount of water as it does metal to the same temperature.

Detailed explanation-2: -Each different type of metal causes the temperature of the water to increase to a different final temperature. This indicates that each metal has a different ability to absorb heat energy and to transfer heat energy.

Detailed explanation-3: -Heat flow stops when the two systems reach the same temperature. In other words, now the two systems are in thermal equilibrium with each other and there is no more heat flow taking place between the two systems.

Detailed explanation-4: -In general, metals feel colder or hotter to the touch than other materials at the same temperature because they’re good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects.
