If a balloon is squeezed, what happens to the pressure of the gas inside the balloon?
2 answers:
Answer: 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.

Answer:
3.74 x 10²² particles
Explanation:
Given parameters:
Mass of compound = 1.43g
Molar mass of compound = 23g
Unknown:
Number of particles of sodium = ?
Solution:
To find the number of particles of Na in the compound, we need to obtain the mass of sodium from the total mass given;
Mass of sodium =
=
= 1.43g
Now find the number of moles of this amount of Na in the sample;
Number of moles = =
= 0.062mole
Now;
1 mole of substance = 6.02 x 10²³ particles
0.062 mole of substance = 0.062 x 6.02 x 10²³ particles
= 3.74 x 10²² particles
