1. decreases.
According to Boyle's Law, the relation between pressure and volume cab be stated as PV = k, where P is the pressure inside the container and V is the volume of the container.
So, pressure and volume are inversely proportional. If volume decreases pressure in the container increases and vice-versa. But this law is obeyed until the temperature and amount of gas remain unchanged.
2. Solids
Only solids are the substances which have fixed volume, changing shape and are not compressible.
3. 22.4 liters
At STP (Standard Temperature and Pressure), one mole of any ideal gas occupies a volume of approximately 22.4 liters.
4. D.
According to the kinetic Molecular Theory, solid's molecules move very quickly with high kinetic energy.
5. direct
Temperature and volume have direct relationship according to ideal gas law equation PV = nRT. We can see that temperature (T) and volume (V) are directly related.
6. Indirect
Pressure and volume have direct relationship according to ideal gas law equation PV = nRT. We can see that Pressure (T) and volume (V) are indirectly related.
7. P1 V1/n1 T1 = P2 V2/n2 T2
As the values V = 0.35 L, T = 18. degree celsius and P = 980 mmHg and constant R = 8.314 J/(mol·K), we can easily find V2 easily.
8. PV = nRT
The ideal gas law equation PV = nRT can be used fing V as the values for P, T, n are given in the problem and R value is a constant.
