PV = constant for a given temperature. Why does an increase in volume correspond to a decrease in pressure?
|
Because the molecules strike the container wall less often.
|
What is the ratio of the number of oxygen molecules to the number of hydrogen molecules? - They Both Have Equal Volumes, but different molecular masses
|
The ratio is 1:1 this is because PV = nRT
|
What happens to the average speed of the molecules, when a sample of ideal gas is heated and its Kelvin temperature doubles?
|
It changes, but it does not double or half.
|
Why don't ocean temperatures vary drastically?
|
Because Water has a relatively high specific heat.
|
Where can convention occur?
|
Only in liquids and gases.
|
In a cloud formation, water vapor condenses into water droplets which get bigger and bigger until it rains. This will cause the temperature of the air in the clouds to .......?
|
It will cause the temperature of the air in the clouds to increase.
|
A chunk of ice (T = -20C) is added to a thermally insulated container of cold water (T = 0C). What happens in the container?
|
Some of the water freezes and the chunk of ice gets larger.
