What is steam?
Two identical samples of water are placed on hot plates. Sample A is placed on a 500 degree hot plate. Sample B is placed on a 300 degree hot plate. Both samples are boiling, so this sample is the hotter sample.
What is neither?
What is bigger?
What is 4,184,000 J?
Two objects are in contact and come to thermal equilibrium, which means this value must be the same for both objects
What is their temperature?
A 0.00016 kg sample of helium gas is cooled from 300 K to 4 K, which requires this much energy to be removed
This feature of a heating curve is related to the specific heat of the material
What is the slope?
This material contracts when heated from 0 to 4 degrees Celsius
What is liquid water?
An instant hot pack forces your skin to go through this kind of process
What is endothermic?
A 45 degree change in Fahrenheit temperature is a change by this many degrees Celsius
What is 25 degrees Celsius?
10 grams of solid gray metal is heated to 100 degrees Celsius and placed in 100 grams of water at 25 degrees Celsius. The mixture reaches a final temperature of 25.22 degrees Celsius, which means this is the identity of the metal
What is lead?
It takes this much energy to boil a 2.00 kg sample of liquid nitrogen
What is 402,000 J?
A electricity wire is hung during summer and is 15 feet above the ground. During the winter, a 15-foot tall truck attempts to drive under the wire, causing this interaction
What is none?
Lifting a 100 kg barbell 1.00 meters 100 times will require this many Calories, assuming no work is done by you to lower the barbell
The same amount of energy used to heat a sample of water up by 1 degrees Celsius would heat a sample of iron by this many degrees Celsius
What is approximately 10 degrees Celsius?
A 1.00 kg iron pan must be this temperature to have enough energy to heat 100 g of water from 25 degrees Celsius to 100 degrees Celsius.
Assume the iron pan's final temperature is also 100 degrees Celsius
What is 170 degrees Celsius?
A 1.00 kg sample of water is heated from -40 degrees Fahrenheit to 400 degrees Celsius, which required this much energy
Water has a thermal volume expansion coefficient of 210 x 10-6. If the Earth's oceans have a volume of 1.386 x 1021 L, this is how much more volume the oceans will have if global temperatures rise by 2.0 oC
What is 5.82 x 1017 L?
A sample of water sits at room temperature as some of the water evaporates. The rest of the liquid water is undergoing one of these processes.
What is exothermic?
A room at 70 degrees Fahrenheit is this many degrees Rankine
What is 530 degrees Rankine?
A cheeto is burned and all of the heat from burning it is used to heat up a 100 g sample of water from 24 degrees Celsius to 100 degrees Celsius, which means a single Cheeto has this many Calories.
What is 7.6 Calories?
