Temperature
These two temperature scales have degrees which are equivalent in magnitude.
What are the Celsius and Kelvin scales?
It takes this many calories to raise the temperature of 1gram of water 1 degree Celsius.
What is 1 calorie?
A substance with a low specific heat capacity will absorb or release a small amount of heat while having this kind of temperature change.
What is a large temperature change?
A bimetallic strip is made of steel on one side and copper on the other. As it is heated it will bend to this side because this metal has the lower specific heat capacity and expands faster.
What is the steel side?
The temperature at which water is the most dense is this.
What is 4 degrees Celsius?
The molecules of air in this room have this kind of velocity.
What is a variety of velocities?
It would take this many Joules to raise the temperature of 10 grams of water 10 degrees Celsius.
What is 419 degrees Celsius?
Wesley is welding and a spark lands on his arm causing him a small flash of pain, but resulting in no visible burn. This is because steel has this kind of specific heat capacity resulting in a small amount of energy transferred as heat for a large change in temperature.
What is a low specific heat capacity?
This phase of matter generally expands more than the other phases when subjected to an equal rise in temperature.
What is a gas?
If the temperature of water in a glass is 4 degrees Celsius, and it experiences a small fluctuation in temperature either up or down by a degree or two, its volume will do this.
What is increase?
There are several kinds of molecular motion, including rotational, vibrational and translational. The type that mostly relates to temperature is this kind.
What is translational motion?
A cup of hot chocolate and an iceberg both have internal energy. This one has more.
What is the iceberg?
Water moderates the climates of bodies of land that it surrounds because of this.
What is its high specific heat?
If glass expanded more that alcohol, then the column of alcohol in a thermometer would fall when the temperature did this.
What is rose?
This property of ice results in a decrease in the density of the ice.
What is the presence of open spaces in the ice crystals formed?
Temperature is a measurement of this kind of molecular energy.
What is kinetic energy?
This much heat is needed to raise 1 kg of water 20 degrees Celsius.
What is 20 kilocalories? or
20,000 calories, or
83,800 Joules
100 grams of water cools off by 1 degree Celsius. This much heat is given off in Joules.
What is about 418 Joules?
Bob heats up a metal ring. As the ring increases in temperature and then cools, this is what happens to the diameter of the opening in the ring.
What is that it first increases and then decreases?
There is a giant inland sea or lake on the continent of Antarctica. The temperature of the water at the bottom of this lake at this moment is this.
What is 4 degrees Celsius?
A cup of boiling hot apple cider has a different amount of internal energy than a pot of boiling hot apple cider. This one has a greater temperature.
What is neither?
When you touch a cold flag pole in winter with your tongue, energy flows in this way.
What is from your warm tongue to the flag pole?
In terms of types of internal energy, water has a high specific heat because of this.
What is that water absorbs large amounts of energy in the form of internal vibrations and rotations?
If an ice cube is taken from a 20 degree Fahrenheit freezer and placed in a 10 degree Fahrenheit freezer, this will happen to its density.
What is that thermal contraction will take place and it will become more dense?
When ice water at 0 degrees Celsius is heated, describe what takes place in terms of thermal contraction and thermal expansion.
What is that both take place until the temperature reaches 4 degrees Celsius?
