Question

A 0.03 kg silver fork cools from 373.15 K to 323.15 K. How much heat is lost by the fork? Specific heat of silver is 235 J/kg*K.

Answer 1

The silver fork loses 352.5 Joules of heat.

Step-by-step explanation:

To determine the amount of heat lost by the silver fork, we can use the formula:

Q = m × c × ΔT

Where:

• Q is the amount of heat lost
• m is the mass of the silver fork (0.03 kg)
• c is the specific heat of silver (235 J/kg·K)
• ΔT is the change in temperature (373.15 K - 323.15 K = 50 K)

Plugging in the values, we get:

Q = 0.03 kg × 235 J/kg·K × 50 K = 352.5 J

Therefore, the silver fork loses 352.5 Joules of heat.
