he actual mass of water that could be heated by 30.0℃ using 62 900J of input thermal energy is _______ g. (Record your three-digit answer with no units in the space below.)

An unknown material with a mass of 1 kg is heated from 600C to 1000C. The amount of heat energy required was 15.2 kJ. Calculate the specific heat and identify the material.

Newton's Law of Cooling  The temperature of a cup of coffee t min after it is poured is given by the following equation where T is measured in degrees Fahrenheit. T = 65 + 110e−0.053t (a)What was the temperature (in degrees Fahrenheit) of the coffee when it was poured?_________ °F (b)When (in minutes) will the coffee be cool enough to drink (say, 120°F)? (Round your answer to one decimal place.)_______ min

An unknown hot metal at 148.7°C with a mass of 49.6g was mixed with 28.61g of water at an initial temperature of 19.74°C.  A final temperature (for both water and metal) of 27.71°C was reached. In units of J/(g°C), what is the specific heat of the unknown metal?  Note: In the space below, please enter you numerical answer.  Do not enter any units.  If you enter units, your answer will be marked as incorrect.

What is the standard unit of temperature in the SI? (Do not abbreviate; for example gram not g.)

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.)

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation PV = 8.31T, where P is measured in kilopascals, V in liters, and T in kelvins. Use differentials to find the approximate change in the pressure if the volume increases from 10 L to 10.6 L and the temperature decreases from 335 K to 330 K. (Note whether the change is positive or negative in your answer. I Round your answer to ti decimal places.

50 milliliters of water at 60°c is added to 75 ml of water at 30°c in a coffee cup calorimeter. the resulting mixture was observed to have a temperature of 40°c. what is the calorimeter constant?

Subject: Differential Equations Yoon Se-Ri is baking a cake for Captain Ri Jeong-Hyeok in a kitchen whose ambient temperature is 71.79 °F. She removed the cake from the oven whose temperature is 410 °F. The cake's temperature dropped to 350 °F after 8.1 minutes. What will be the cake's temperature after 0.23 hours?   Round your answer to 2 decimal places.

How much energy (in MJ) is needed to raise the temperature of 0.234 m3 of water from 15.1˚C to 76.2˚C [round your final answer to one decimal place]?   {specific heat of water = 4,180 J/(kg∙˚C); density of water = 990.1 Kg/m3}
