Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. use the following
specific heat capacity data to determine which block will increase its temperature the most
iron
substance specific heat capacity (cal/g*c)
0.11
copper 0.09
silver 0.06
lead 0.03
iron
copper
silver
lead

The change in temperature will be highest for lead metal

Explanation:

To calculate the heat absorbed or released, we use the equation:

where,

q = heat absorbed = 200.0 J

m = mass of the substance

C = specific heat of substance

= change in temperature

As, amount of heat is getting absorbed and mass is same in all the cases. So, the change in temperature will depend only on the specific heat.

From above, it is visible that change in temperature is inversely related to specific heat. So, more is the specific heat, less will be the temperature change.

For the given options:

The specific heat of lead is the lowest which is 0.03 Ca/g°C

Hence, the change in temperature will be highest for lead metal

you would expect a sound wave to speed up. - b)

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
