Physics Change in Temp

Question

Use the formula to find how many cal it takes to raise the temperature of 200 g of water from 20∘C∘C to 25 ∘C∘C. For the specific heat capacity c, use 1 cal/g⋅∘Ccal/g⋅∘C.

Q=cmΔT

Answer 1

Hi Willowanne,

That's pretty straight forward.

Apply the formula: Q=cmΔT

Q = 1 cal/g⋅∘C * 200g * (25 - 20) ∘C

= 1000 cal.
