Homework Answers
The correct option is both (a) and (d).
EXPLANATION: By ideal gas law, PV = nRT. So, for a fix amount of gas,
- Pressure, P
Temperature, T at constant volume - Pressure, P
1/Volume, V at constant temperature
Temperature, T at constant volumeSo, if we decrease the volume, V by keeping the temperature, T constant than the pressure will be increased. In the same manner, if we increase the temperature by heating keeping the volume constant, pressure will be increased. Hence, the correct option is both a and d.

A 1.72 mol sample of Kr gas is confined in a 40.4 liter container at 13.2 °C. If the amount of gas is decreased to 0.860 mol, holding the volume and temperature constant, the pressure will decrease because: Choose all that apply. As the number of molecule-wall collisions increases, the force per collision decreases. With fewer molecules per unit volume, the molecules hit the walls of the container less often. With lower average speeds, on average the molecules hit the...
