Name two properties of an “ideal” gas.
600
Answer: they have zero kinetic energy (no velocity)
What happens to molecules at absolute zero?
800

What causes a gas to exert pressure?
200
Answer: Kelvin
What unit must temperature always be in for all gas law calculations?
400
Answer: 273
What must be added to the Celsius temperature to convert it to Kelvin?
600
Answer: 460 kPa
4.5 atm = ? kPa
1.00 atm = 760. mmHg = 101.325 kPa = 29.92 inHg = 14.7 psi | TK = TC + 273 | ||
| | | STP 1 atm & 0 oC |
800
Answer: 1150 mmHg
153 kPa = ? mmHg
1.00 atm = 760. mmHg = 101.325 kPa = 29.92 inHg = 14.7 psi | TK = TC + 273 | ||
| | | STP 1 atm & 0 oC |
