Answer #1

A serving of Cheez-Its releases 130 kcal of heat energy (q).

i.e. q = 130 kcal

Formula: q = m.C.T

Where 'm' is the mass of water = 10 kg

'C' is the specific heat capacity of water = 1 kcal/kg.oC

T is the change in temperature of the water

Now, 130 kcal = 10 kg * 1 kcal/kg.oC * T

Therefore, T = 13 oC or 13 K
