| the temperature of a gass is proportional to the | average kenetic energy of the gas molecules
🗑
|
||||
| the kinectic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of | molecules moving a little farther apart
🗑
|
||||
| two degree intervals on the celsius temperature scale are | equivalent to 3.6 farenheit degree intervals
🗑
|
||||
| a temperature reading of 2*c is | equivalent to 35.6*F
🗑
|
||||
| the temperature known as room temperature is nearest to | 20*c
🗑
|
||||
| using the absolute temperature scale, the freezing point of water is correctly written as | 273 K
🗑
|
||||
| the metric unit of heat called a calorie is | all of the above (specific heat of water, energy needed to increase the temp of 1 gram of water 1 degree celsius, equivalent to a little over 4 joules of mechanical work)
🗑
|
||||
| which of the following is a shorthand way of stating that the temperature change of a substance is directly proportional to the quantity of heat added | Q 8 delta T
🗑
|
||||
| the quantity known as specific heat is | the energy needed to increase the temp of 1 gram of a substance 1 degree celsius
🗑
|
||||
| if 1 kg of soil and 1kg of water each recieve 1 kcal of energy, ideally | the soil will be 5*c warmer than the water
🗑
|
||||
| the heat transfer that takes place by energy moving directly from molecule to molecule is called | conduction
🗑
|
||||
| the heat transfer that does not require matter is | radiation
🗑
|
||||
| styrofoam is a good insulating material because | it contains many tiny pockets of air
🗑
|
||||
| the transfer of heat that takes place because of density difference in fluids is | convection
🗑
|
||||
| when a solid, liquid, or a gas changes from one physical state to another, the change is called, | a phase change
🗑
|
||||
| latent heat is "hidden" because it | goes into or comes out of internal potential energy
🗑
|
||||
| as a solid undergoes a phase change to a liquid state, it | absorbs heat while remaining at a constant temperature
🗑
|
||||
| the condensation of water vapor actually | warms the surroundings
🗑
|
||||
| water molecules move back and forth between the liquid and the gaseous state | at all times with evaportaion, condensation, and saturation defined by the net movement
🗑
|
||||
| no water vapor is added to or removed from a sample of air that is cooling, so the relative humidity of this sample of air will | be higher
🗑
|
||||
| compared to cooler air, warm air can hold | more water vapor
🗑
|
||||
| a heat engine is designed to | convert heart into mechanicla energy
🗑
|
||||
| the work that a heat engine is able to accomplish is ideally the equivalent to the | difference in the heat supplied and the heat rejected
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
