Question

Given that water has a specific heat capacity of 4.184 j/g celsius, calculate the amount of heat (j) to raise the temperature of 250.0 g of water 24.00 celcius

Answer 1

In this question, we have to use the Calorimetry formula, which is the formula that perfectly correlates the change of temperature, mass and specific heat capacity of a specific substance, the formula is the following:

Q = mcΔT

We have:

m = 250g

c = 4.184 J/g°C

ΔT = 24°C

Now we add these values into the formula:

Q = 250 * 4.184 * 24

Q = 25104 J or 25.1 kJ will be the amount of heat
