Final answer:
The temperature change is calculated to be approximately 2.38°C.
Step-by-step explanation:
To calculate the temperature change when 1000J of heat is supplied to 100g of water, you can use the formula:
ΔT = Q / (m * c), where ΔT is the change in temperature, Q is the heat supplied, m is the mass of the water, and c is the specific heat capacity of water.
Given:
Q = 1000J
m = 100g (which is 0.1kg)
c = 4200J/kg°C
The specific heat of water is often approximated as 4.184 J/g°C for calculations, so we can use either value given the same units are applied throughout.
ΔT = 1000J / (0.1kg * 4200J/kg°C)
ΔT = 1000J / (420J/ °C)
ΔT = 2.38°C
Therefore, the temperature change is approximately 2.38°C when 1000J of heat is supplied to 100g of water.
