Question

Calculate the quantity of thermal energy that is absorbed when the temperature of 12.5 g of nickel increases by 2.5 degrees C. The theoretical specific heat capacity of nickel is 0.444 J/g degrees C.

Answer 1

The nickel absorbs 13.875 joules of thermal energy when the temperature of 12.5 g of it increases by 2.5 degrees Celsius, using the specific heat capacity of 0.444 J/g°C.

Step-by-step explanation:

To calculate the quantity of thermal energy absorbed by nickel when its temperature increases, you can use the formula:
Q = mcΔT, where:

For the case of 12.5 g of nickel increasing by 2.5 degrees Celsius and a specific heat capacity of 0.444 J/g°C, the thermal energy is calculated as follows:

Q = (12.5 g) × (0.444 J/g°C) × (2.5 °C)
Q = 13.875 J

Therefore, the nickel absorbs 13.875 joules of thermal energy.
