1. What is 300 degrees Celsius in Kelvin?
2. What is 300 degrees Kelvin in Celsius?
3. What is 0 degrees Celsius in Kelvin?
4. What is 0 degrees Kelvin in Celsius?
5. A gas has a pressure of 2 atmospheres and 400 ml of volume. If the pressure is doubled to 4 atmospheres, what happens to the volume?
6. A gas has a pressure of 450 mm of mercury (Hg) and 400 ml of volume. If the pressure is change to 760 mm of mercury, what happens to the volume?
7. A gas has a volume of 500 ml at 273 K, What is the volume if the temperature is changed to 373 K
8. A gas has a temperature of 25 degrees Celsius and a volume of 35 L. What happens to the volume is the temperature becomes 1 degree Celsius.
1. The pressure and temperature of a gas are indirectly proportional
If the gas pressure is halved then the volume is doubled if the temperature remains the same.
V1P1
= V2P2
2. The temperature and volume of a gas are directly proportional.
If the temperature of a gas is doubled then the volume is doubled if the pressure remains the same.
V1 = V2
T1
T2
Standard pressure is 1 atmosphere (atm) or 760 mm Hg
When doing gas calculations the Celsius temperature must be changed to Kelvin.
Kelvin = Celsius + 273
Celsius = Kelvin –273
Standard Temperature is 0 degrees celsius or 273 K
STP means standard temperature and pressure
1. What is 300 degrees Kelvin in Celsius?
2. A gas has a pressure of 600 mm of mercury (Hg) and 20 ml of volume. If the pressure is change to 660 mm of mercury, what happens to the volume?
3. A gas has a volume of 225 ml at 73 oC, What is the volume if the temperature is changed to 102 oC
