If a cube of a certain metal increases its volume from 15 cm3 to 17 cm3 as the temperature increases from 12°C to 28°C, what is the metal's linear expansion coefficient?
An object absorbs 1.70×104J of heat and as a result, its temperature is increases from 45.0∘C to 75.0∘C. What is its heat capacity of the object?
You heat 1 L of water and its temperature increases to 10 ° C. if the same heat is applied with 2 L of water. How much did the temperature rise? to 3 L of water? Write your response next to the blank spaces below. 1L = 10°C 2L = 3L = 2. a Big bucket contains 1 L of water at 20 ° C. What will be the temperature of the mix when 1 L of water at 20...
8. a. Given that the specific heat of one material is twice that of another compare the amounts of heat required to raise the temperatures of equal masses of each material by 1°C. b. If the same amount of heat were added to samples of both materials and each sample had the same increase in temperature, compare the masses of each sample.
How much heat does 29.0 of water absorb, if its temperature increases from 20.0 C to 46.0 C ? The specific heat capacity of water is 4.18 J/(g.C)

A sample of carbon monoxide gas is heated at constant pressure until its temperature increases by 62.3 degree C. A sample of neon gas is heated at constant volume until its temperature increases by 22 degree C. If each sample of gas absorbs the same amount of heat, what is the ratio of the number of moles of neon to the number of moles of carbon monoxide?
For an ideal gas, whose temperature increases from T1 to T2, what would be its enthalpy change? (a) Cv (T2-T1) (b) Cv (T1-T2) (c) Cp (T2-T1) if the heat capacities stay constant during the temperature range
A liquid has its temperature raised from 15°C to 65°C by passing it through a heater in which the heating surface is maintained at 125°C by condensing steam. If the overall coefficient of heat transfer can be assumed to vary as the velocity raised to the power 0.8, what will be the exit temperature of the liquid if its velocity is doubled? Assume liquid thermal properties are temperature-independent over the range concerned. [ans. 60.15 C]
