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.
