• 7.45 L

• 0.0190 L

• 251 L

A scuba tank has a pressure of 195 atm at a temperature of 10 C. The volume of the tank is 350 L. How many moles of air are in the tank? 

• 0.000340 mols
• 83130 mols
• 2937 mols
• 19.80 mols

• 1.52 atm
• 2.23 atm
• 4.46 atm
• 7.89 atm

• 11.24 L
• 26.52 L
• 24.54 L
• 39.41 L

According to Boyle's law, at constant temperature, as the pressure of a given sample of gas is increased, the volume will –

• Increase
• Decrease
• Remains the same

As per Charles' Law if temperature of any gas is increased its volume will -

• increase
• decrease
• remain the same
• double

In following diagram A, B, C, and D (assume left most A and so forth with right most D) the arrows are showing –

• Decrease in energy thus more particle movement during change in state of matter
• Increase in energy thus less particle movement during change in state in state of matter
• Decrease in energy thus less particle movement during change in state of matter.
• Increase in energy thus more particle movement in each new state than before during the change in the state of matter.

Boyle's law : When _______ is held constant, the pressure and volume of a gas are ________  proportional

• temperature,  equally
• mass, inversely
• temperature, inversely
• mass, equally
