A wooden block has a mass of 1.2 kg and a specific heat of 1700 J/(kg o C). Find the change in thermal energy of the block as it warms from 10 o C to 15 o C.

1 answer

To find the change in thermal energy of the block as it warms from 10°C to 15°C, we can use the formula:

ΔQ = mcΔT

Where:
ΔQ = change in thermal energy
m = mass of the block (1.2 kg)
c = specific heat of the block (1700 J/(kg o C))
ΔT = change in temperature (15°C - 10°C = 5°C)

Plugging in the values:

ΔQ = (1.2 kg)(1700 J/(kg o C))(5°C)
ΔQ = 10200 J

Therefore, the change in thermal energy of the block as it warms from 10°C to 15°C is 10200 Joules.
