Answer: 0.023 liters
Explanation:
Given that,
Original volume of gas (V1) = 25mL
[convert 25mL to liters
If 1000ml = 1L
25ml = 25/1000 = 0.025L]
Original temperature of gas (T1) = 22°C
[Convert 22°C to Kelvin by adding 273
22°C + 273 = 295K]
New volume of gas (V2) = ?
New temperature of gas (T2) = 0°C
[Convert 0°C to Kelvin by adding 273
0°C + 273 = 273K]
Since volume and temperature are given while pressure is held constant, apply the formula for Charle's law
V1/T1 = V2/T2
0.025L/295K = V2/273K
To get the value of V2, cross multiply
0.025L x 273K = 295K x V2
6.825L•K = 295K•V2
Divide both sides by 295K
6.825L•K/295K = 295K•V2/295K
0.023 L = V2
Thus, the new volume of the gas will be 0.023 litres

Answer::Democritus
Explanation
The idea that all matter is made up of tiny, indivisible particles, or atoms, is believed to have originated with the Greek philosopher Leucippus of Miletus and his student Democritus of Abdera in the 5th century B.C. (The word atom comes from the Greek word atomos, which means “indivisible.”) These thinkers held that,
