If the pressure acting on a given sample of an ideal gas at constant temperature is tripled, then

Explanation:

The question relates to Boyle's law which states that at constant temperature the volume of given mass of gas is inversely proportional to the pressure

V  = K/p

PV = K

P₁V₁ = P₂V₂ where P₁ = P atm ( pressure) P₂ = 3P

then P V₁ = 3P V₂

V₂ = V₁ / 3 so the volume is reduced to one-third its original volume.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
