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

Respuesta :

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
