A piece of glass has a temperature of 77.0 °C. Liquid that has a temperature of 39.0 °C is poured over the glass, totally covering it, and the temperature at equilibrium is 50.0 °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, decide the specific heat capacity of the liquid.
