suppose a 375-ml sample of neon gas at 78 c is cooled to 22 c at constant pressure. what will he the new volume of the neom sample

The new pressure is 315.17 ml

Calculation

The new pressure is calculated using Charles law formula

that is V1/T1 = V2/T2 where,

V1 = 375 ml

T1 = 78 °C into kelvin = 78 + 273 = 351 K

V2=?

T2 = 22 °c into kelvin = 22 + 273 = 295 K

make V2 the subject of the formula by multiplying both side by T2

V2 = T2V1/T1

V2 = [ (295 K x 375 ml) / 351 k] = 315.17 ml
