A piece of glass has a temperature of 90.0 °C. Liquid that has a temperature of 32.0 °C is poured over the glass, completely covering it, and the temperature at equilibrium is 55.0 °C. The mass of the glass and the liquid is the same. Ignoring the container that holds the glass and liquid and assuming that the heat lost to or gained from the surroundings is negligible, determine the specific heat capacity of the liquid.
Homework Answers
: By Q(lost) by glass = Q(gained) by
liquid
=>m x c(glass) x delta t*C = m x c(liquid) x delta t*C
=>840 x (90-55) = c(liquid) x (55-32)
=>c(liquid) = 1278.26 J/(kg·*C)
