In an insulated vessel, 250 g of ice at 0°C is added to 600 g of water at 18.0°C. (a) What is the final temperature of the system? (b) How much ice remains when the system reaches equilibrium?
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
(a) What is the final temperature of the system?
(b) How much ice remains when the system reaches equilibrium?
Given that
Mass of the ice is m1 = 250 g
Initial temperature of ice = 0
Mass of the water m2 = 600 g
Initial temperature of water is =
Constant material depended parameters are
Specific heat of water s = 1 cal/g/
Latent heat melting of ice is L = 80 cal/g
Part a:
The heat will supply to the ice by the water.
The heat released by the water in the conversion from .
Now the amount of Ice melt by absorbed heat 10800 cal from water is,
Now after this conversion
Ice of temperature 0 remains in the system = (250-135) = 115 g .................(1)
Water of temperature remains in the system = (600+135) = 735 g
Now in the system, Ice of and water of temperature are present so the heat transfer from water to ice make same amount of ice and water in the system.
Above equation is at constant equilibrium temperature of
