1. a balloon with a fixed amount of air is at room temperature. the balloon is placed in a pan of hot water. • describe what happens to the balloon in the hot water. • explain what happens to the pressure, volume, and temperature of the gas inside the balloon. • explain what happens to the air molecules inside the balloon.

The volume occupied by the air inside the balloon and pressure exerted by the air particles on the walls of ballon will get increased.

Explanation:

The temperature of the hot water is higher than the room temperature.

When the balloon with fixed amount of air kept in the hot water. The volume occupied by the air inside the balloon will increase because the temperature of the hot water is more than that of temperature of room temperature.

This is because the volume occupied by the gas is directly proportional to the temperature at constant pressure (Charles law).

The pressure on the balloon from the external source will remain unchanged but the pressure exerted by the air particles on the walls of balloon will get increased as the volume of the balloon is increasing.

The average kinetic energy of the gas molecules will get increased in hot water as kinetic energy of the gas molecule increases with increase in temperature and it is given by:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
