If a balloon is squeezed, what happens to the pressure of the gas inside the balloon? a. it increases. b. it stays the same. c. it decreases. d. the pressure depends on the type of gas in the balloon.

Option (a) is the correct answer.

Explanation:

Pressure is defined as the force applied on per unit area.

Mathematically,          Pressure =

When we squeeze a balloon then it means we are applying pressure on it. Also, we are decreasing the area of balloon by applying more amount of force on it.

As area is inversely proportional to pressure. So, a decrease in area will lead to an increase in pressure.

Hence, we are increasing the pressure on the balloon by squeezing it.

Thus, we can conclude that if a balloon is squeezed, then pressure of the gas inside the balloon increases.

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
