Heat Transfer Equation

  • 0 votes

Equation = XH=mCXT

XH= energy change   m= mass of water being heated  C=specific heat capacity of water    XT= change in temperature

Specific heat capacity= amount of energy (J) needed to increase temperature of 1g/1cm^3 of water by 1 degrees celcius. 

If the question is :    600cm3 of water, temperature raised by 60 degrees celcius, how much energy had been transferred to water, in kJ?

 

The answer is 148.32 by how do you get to that and how do you work out the specific heat capacity?

The specific heat capacity of water is 4200j/Kg'C, I think you would be given the specific heat capacity in a question like this.

Try this question 

the specific heat capacity of seawater is 3900J/Kg'C. how much energy is needed to heat 500g of seawater from 20'C to 90'C?
