If you wish to warm 150 kg of water by 20°C for your bath, show that the amount of heat needed is 3000 kcal (3000 Cal, more than the amount of food energy the average human needs per day!). Then show that this is equivalent to about 12,600 kJ.

Imagine a swimming pool 25 m long and 15 m wide. If the water is exactly 2 m deep when the water temperature is 20 ° C, how deep will the water be if the temperature increases to 21 ° C?
The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?
A very hot piece of iron is placed in 200 mL of water. The water is initially at 20°C and heats up to 37 C. Remembering that water has a specific heat of 1 cal/(g* C), how much heat did the water gain? Q = %3D unit The iron had a mass of 290 grams. Iron has a specific heat of .11 cal/(g*° C). Assuming that iron lost all of the heat the water gained and also reached a final temperature of 37 ° C, what was its initial temperature? T = unit ?
When you turn your hot water on in the shower, it takes a bit for the water to get warm. Some of this is because the water in the pipe is cold but some of it is because the water from the hot water heater must heat the copper plumbing pipe itself. Copper has a specific heat of 0.39R. How much energy does it take to heat 2 kilograms of copper pipe from 70°F to 130°F? Report your answer in Joules. (Hint: Note that you'll need to convert kJ to J and F to K.)
How much energy in kJ is needed to raise the 12 kg of now gaseous nitrogen N, from boiling temperature, -196 °C, to room temperature, 20°C.? The specific heat of nitrogen gas is is c = 1,004 Joules/kg°C.
Suppose we have a piece of a candy bar that has an initial mass of 28g. If we ignite the piece of candy bar (literally burn it), and it increases the temperature of 341.42g of water from 18.11°C to 69.72°C, how many calories per gram of energy did the candy bar provide if the final mass of the marshmallow is 3.92? Note: 1.00 cal = 4.184 J. Give your answer in units of cal/g.
1) A blacksmith heats a 2.5kg piece of steel of 850 degrees Celisus, then allows it to cool to room temperature (20oC). How much heat is released as it cools? (The specific heat of steel is 466 J/kg.0C) 2) A small brass ring has a mass of 0.02 kg. A scientist measures that 342 J of heat are required to increase it temperature by 45oC. Based on this information, what is the specific heat of brass? Questions 5-7, the following values will be needed: Specific heat of liquid water: 4,186 J/kg.0C Heat of vaporization of water: 226,000 J/kg Boiling point of water: 1000C A tea kettle holds 0.6kg of water at 250C. It is placed on a stove until the water has entirely boiled and tuned to steam 5. How much heat is required to raise the temperature of water to its boiling point 6. How much heat is required to fully vaporize the water? 7. What is the total energy absorbed by the water during this process?
Suppose you eat a breakfast snack that has 3 servings worth of food and that each serving is 750 calories. (1 Kilo-Calorie = 1000 calories). How much energy in terms of Joule would you get from eating the entire snack? (1Kilo-Calorie = 4184 Joule).
A Pyrex baking dish with a mass of 545g warms up by 96.7 eC when it absorbs s0.9 kJ of heat an oven. What is the specific heat capacity of the dish in J/g°c? Tc0, 9222 56S b) If 7.5 kg of ice at O°C is put into an icebox, how many joules of heat are absorbed from the other items in the icebox as the ice melts? (For H2O, AHus Lt 334.7 J/g & AHvap Ly 2259.4 J/3) c) How much energy Joules) is required to boil off 1 gallon (3786g) of water that starts out at 21.50C? (See pt. b above for useful constant.)
