How much heat Q is required to change 27.0 g of ice at −5.00∘C to 27.0 g of steam at 122∘C?

A thirsty nurse cools a 2.40 L bottle of a soft drink (mostly water) by pouring it into a large aluminum mug of mass 0.249 kg and adding 0.122 kg of ice initially at -14.3 ∘C. If the soft drink and mug are initially at 21.0 ∘C, what is the final temperature of the system, assuming no heat losses? Express your answer in degrees Celsius.

One gram of water is vaporized into 1.65×103 cm3 when boiled at a constant pressure of 1.013×105⁢P⁢a. If the heat of vaporization at this pressure is Lv=2.256×106⁢J/k⁢g, what is the work done by the water when it vaporizes?

What mass of water at 20.0°C must be allowed to come to thermal equilibrium with a 1.95-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 60.0°C? Assume any water turned to steam subsequently recondenses. kg

If you have 6 moles of a diatomic ideal gas (such as oxygen or nitrogen), how much heat is required to raise the temperature of this gas from 261.5K to 282K if the volume of the gas remains constant during the heating?

A copper block with a mass of 400 grams is cooled to 77 K by being immersed in liquid nitrogen. The block is then placed in a Styrofoam cup containing some water that is initially at +50.0°C. Assume no heat is transferred to the cup or the surroundings. The specific heat of liquid water is 4186 J/(kg °C), of solid water is 2060 J/(kg °C), and of copper is 385 J/(kg °C). The latent heat of fusion of water is 3.35 x 105 J/kg. What is the mass of water in the cup, if the final temperature is -25.0°C?

Indigenous people sometimes cook in watertight baskets by placing hot rocks into water to bring it to a boil. What mass of 500.0C rock must be placed in 4.00 kg of 15.0C water to bring its temperature to 100.0C, if 0.0250 kg of water escapes as vapor from the initial sizzle? You may neglect the effects of the surroundings and take the average specific heat of the rocks to be that of granite.

Super Invar, an alloy of iron and nickel, is a strong material with a very low coefficient of thermal expansion (0.20×10^6 C∘). A 2.5 m long tabletop made of this alloy is used for sensitive laser measurements where extremely high tolerances are required.How much will this alloy table expand along its length if the temperature increases 6.0 C∘?How much will a 2.5m long table made of steel expand along its length if the temperature increases 6.0 C∘?

What mass of water at 20.0°C must be allowed to come to thermal equilibrium with a 1.90-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 70.0°C? Assume any water turned to steam subsequently recondenses. kg
