Before brewers had access to propane or natural gas, they would heat large, insulated vats of water by adding hot stones to the water. The stones are heated to 800°C before they are dropped into a particular well-insulated large vat holding 1,200 kg of water at 20°C. If we want to heat the water to 70°C, what mass of stones must be added the the vat? The specific heat of the stone is about 790 J/kg°C and the specific heat of water is 4,186 J/kg°C. Assume the mass of the water does not change and that the vat is a perfect insulator so no internal energy is lost to

The mass of a hot-air balloon and its cargo (not including the air inside) is 200 kg. The air outside is at 10.0C and 101 kPa. The volume of the balloon is 400 m3. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0C is 1.244 kg/m3.)
Convert the following to equivalent temperatures on the Celsius and Kelvin scales: (a) the normal human body temperature, 98.6F; (b) the air temperature on a cold day, 5.00F.
A ceramic container used for melting metals (called a crucible) contains 1.30 kg of a molten metal. The liquid metal cools until it reaches its melting point of 1,749°C. A scientist then measures that 2.99 ✕ 104 J of heat is transferred out of the metal before it completely solidifies. What is the latent heat of fusion of this metal, in J/g? (Be careful with units!)
The specific capacity of water is 4200JKg-1°C-1, and the specific heat capacity of alcohol 2400JKg-1°C-1. Equal masses of water and alcohol in identical containers are each supplied with the same quantity of heat . The temperature of the water rises by 24°C. What is the temperature rise of the alcohol?
The specific heat of aluminum is 0.90 1/3-C. How much heat must be added to a 245-gram aluminum pot containing 556 grams of water to raise the temperature from 22.1°C to 97.4°C? What percentage of this heat is used to heat the aluminum pot? Hint: Apply the Law of Conservation of Energy. The heat required to warm up the pot with the water in it is the same amount of heat that would be required to warm up the put and the water separately. 2. For each of the following experimental errors clearly state if the error would increase, decrease, or have no effect on the specific heat that you determined in today's experiment. You must explain your reasoning
A tin calorimeter cup with a specific heat of 210 J/(kg · °C)contains kerosene with a specific heat of 2,018 J/(kg · °C) at 16.0°C. The combination is heated uniformly so that the temperature changes by 1.30°C per minute. If the cup has a mass of 200 g and contains 900 g of the liquid, determine the rate at which heat energy is added (in W).
One gram of water and 1 gram of soil (“land”) are at a temperature of 20°C (68°F). If 5 calories of heat are added to each, what will be the temperature of the water and what will be the approximate temperature of the soil?
I have a bucket of icewater with 100 grams of ice and 900 grams of liquid water all at zero degrees Celcius. I throw a hot chunk of iron into it (after which no heat enters or escapes the system), and the final temperature is 100 degrees Celcius with the ice having melted and some of the water actually boiling. The mass of the iron is 473 grams, and its initial temperature is 7,646 degrees Celcius. How many grams of water actually boil? (Don't write the unit, just the number.) You'll need these numbers: Specific heat of water: 4.2 J/g/deg Specific heat of iron: 0.46 J/g/deg Heat of fusion of water: 340 J/g Heat of Vaporization of water: 2300 J/g
Sweating is one of the main mechanisms with which the body dissipates heat. Sweat evaporates with a latent heat of 2,430 kJ/kg at body temperature, and the body can produce as much as 1.6 kg of sweat per hour. If sweating were the only heat dissipation mechanism, what would be the maximum sustainable metabolic rate, in watts, if 81% of the energy used by the body goes into waste heat? __________________W
You have a 200g cup of coffee at 70 degrees Celsius. You add 20g of milk to it. The milk is at 10 degrees Celsius. The specific heat of coffee is equal to the specific heat of water (4180 J/kg/C) and the specific heat of milk is about 3800 J/kg/C.) What is the change in the temperature of the coffee? (in degrees Celsius).
One ounce of a well-known breakfast cereal contains 99 Calories (1 food Calorie = 4186 J). If 2.4% of this energy could be converted by a weight lifter's body into work done in lifting a barbell, what is the heaviest barbell that could be lifted a distance of 2.0 m?
A pot with 0.0001m3 of vegetable oil is being heated from 20 degrees Celsius to 100 degrees Celsius. The oil has a density of 925kg/m3 and a specific heat of 1670J/kg degrees Celsius. How much heat must transfer to the oil in order to raise its temperature by that amount?
