A balloon with a volume of 1.50 L is compressed to a volume of 0.50 L (at a constant temperature).

a. Do you expect the pressure of the gas in the balloon to increase or decrease? Why?

Answer : The pressure of gas in the balloon will be increases.

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

From this we conclude that, as the volume of gas increases then the pressure of the gas will be decreases and as the volume of gas decreases then the pressure of the gas will be increases.

As per question, the volume of balloon decreases from 1.50 L to 0.50 L at constant temperature. So, the pressure of gas in the balloon will be increases.

Hnece, the pressure of gas in the balloon will be increases.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
