A 50.0g thermometer is used to measure the temperature of 170 mL of water. The specific heat of the thermometer, which is mostly glass, is 750J/(kgK), and it reads 18.0 ∘C while lying on the table. After being completely immersed in the water, the thermometer's reading stabilizes at 75.6 ∘C. Part A What was the actual water temperature before it was measured?

A 50.0 g thermometer is used to measure the temperature of 200 mL of water. The specific heat of the thermometer, which is mostly glass, is 0.179 cal/(g °C), and it reads 20.0 °C while lying on the table. After being completely immersed in the water, the thermometer’s reading stabilizes at 71.2 °C. What was the actual water temperature before it was measured? Use cwater = 1 cal/(g °C) and ?water

Ideally, when a thermometer is used to measure the temperature of an object, the temperature of the object itself should not change. However, if a significant amount of heat flows from the object to the thermometer, the temperature will change. A thermometer has a mass of 37.0 g, a specific heat capacity of c = 815 J/(kg · C°), and a temperature of 12.0° C. It is immersed in 119 g of water, and the final temperature of the water...

A 32.5-g glass thermometer reads 24.1 ∘C before it is placed in 115 mL of water. When the water and thermometer come to equilibrium, the thermometer reads 41.8 ∘C. Ignore the mass of fluid inside the glass thermometer. The value of specific heat for water is 4186 J/kg⋅C∘, and for glass is 840 J/kg⋅C∘. Part A What was the original temperature of the water?

thermometer A SL.1 g sample of glass, which has a specific heat capacity of 0.670 J-g 1.c1, is put into a calorimeter (see sketch at right) that contains 100.0 g of water. The temperature of the water starts off at 22.0 °C. When the temperature of the water stops changing it's 27.1 °C.

When 1.045 g of K2O is added to 50.0 mL of water at 25.0 ∘C in a calorimeter, the temperature of the water increases to 41.5 ∘C. Assuming that the specific heat of the solution is 4.18 J/(g⋅∘C)J/(g⋅∘C) and that the calorimeter itself absorbs a negligible amount of heat, calculate ΔHΔH in kilojoules/mol for the reaction K2O(s)+H2O(l)→2KOH(aq)K2O(s)+H2O(l)→2KOH(aq) Express the change in enthalpy in kilojoules per mole.

Review | Constants Periodic Table Part A Calorimetry is a method used to measure changes in enthalpy, or heat, that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant volume or "bomb") calorimeters. Bomb calorimeters are used to measure combustion and other gas- producing reactions, in which the reaction is observed in a strong, sealed vessel. A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer, in which energy changes in a...
