WebIf the water is initially at 25°C, and the ice comes directly from a freezer at -15°C. a. What is the final temperature at thermal equilibrium? b. What is the final temperature if only one ice cube is used? [Given: specific heat of water = 4190 J/kg°C specific heat of ice = 2220 J/kg°C latent heat of fusion of ice = 333 x 10J/kg] WebJan 24, 2024 · Ans: It is the pressure at which the liquid will change to vapour without boiling. At critical pressure and critical temperature, the latent heat of vapourization of liquid will be equal to zero. For water, the value of critical pressure is 218 atm, and the value of critical temperature is \ (647\, {\text {K}}.\) Q.5.

WebSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C . In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat capacity is the same as specific heat, but without any dependence on mass.
