Answer:

2.62J of energy will be required to warm a silver metal from a temperature of 25°C to 27.5°C.

How to calculate joules?

The energy required in a calorimetry can be calculated using the following formula:

Q = m × c × ∆T

Where;

  • Q = quantity of heat absorbed or released
  • m = mass of substance
  • c = specific heat capacity
  • ∆T = change in temperature

According to this question, 4.37 g of silver should be heated from 25°C to 27.5°C. The heat required is as follows:

Q = 4.37 × 0.24 × (27.5 - 25)

Q = 1.0488 × 2.5

Q = 2.62J

Therefore, 2.62J of energy will be required to warm a silver metal from a temperature of 25°C to 27.5°C.
