Question: 1 when 106 g of water at a temperature of...
When 106 g of water at a temperature of 23.5 °C is mixed with 63.3 g of water at an unknown temperature, the final temperature of the resulting mixture is 47.9 °C. What was the initial temperature of the second sample of water? (The specific heat capacity of liquid water is 4.184 J/g ⋅ K.)
Initial temperature = °C
You add 100.0 g of water at 56.3 °C to 100.0 g of ice at 0.00 °C. Some of the ice melts and cools the water to 0.00 °C. When the ice and water mixture reaches thermal equilibrium at 0 °C, how much ice has melted? (The specific heat capacity of liquid water is 4.184 J/g ⋅ K. The enthalpy of fusion of ice at 0 °C is 333 J/g.)
Mass of ice = g
3. The salt cesium perchlorate is soluble in
water. When 4.06 g
CsClO4 is dissolved in
105.00 g water, the temperature of the solution
decreases from 25.00 °C to 22.70
°C. Based on this observation, calculate the dissolution enthalpy,
Assume that the specific heat capacity of the solution is 4.184 J g-1 °C-1 and that the energy transfer to the calorimeter is negligible.
