Laws with the proper formulas
100
How many atm are 988 torr?
1.3 atm (Pressure Conversion)
100
Tk= 273+Tc Tc= 272- Tk (Temperature must be in Kelvin. At absolute zero (0 K) all motion stops- atoms no longer vibrate.)
What is both formulas used you convert Kelvin to Celsius and Celsius to Kelvin ?
200
Chlorine gas occupies a volume of 25 mL at 300K. What volume will it occupy at 600K?
50 mL (Charles's Law)
200
P1 V1= P2 V2 (Boyle's Law says that the volume of a gas varies with pressure when the temperature stays the same.)
What is Boyle's Law?
300
A 175 mL sample of neon had its pressure changed from 75 kPa to 150 kPa. What is its new volume?
87.5 mL (Boyle's Law)
300
V1/T1 = V2/T2 (Charles's Law says that the volume of a gas caries with the Kelvin temperatures when the pressure is constant.)
What is Charles's Law?
400
Convert 323 Kelvin to Degrees Celsius
50 Degrees Celsius (Temperature Conversion)
400
1 atm = 101.3kPa = 760 mmHg = 1.013x10^5 Pa
What is Pressure Conversions?
500
V1 T2 = V2 T1 (Charles's Law says that the volume of a gas varies with the Kelvin temperature then the pressure is constant.)
