Question

How much energy is needed to change the temperature of 50. 0g of water by 15. 0 degrees celcius?.

Answer 1

For this, we can use the equation E = mcΔt.

Where E = energy, m = mass of water, c = specific heat capacity of water (4.18), Δt = temperature change (15 degrees or 288 K)

So therefore we do 50 x 4.18 x 288 = 60192 J

Hope this helps, let me know if you have any questions:)
