A gas occupies 135 cm3 at 143. K. At what Celsius temperature will its volume be 140 cm3? Assume that pressure remains constant.

Respuesta :

Answer:

New temperature T2 = -124.7 °C

Explanation:

Given:

Old volume V1 = 135 cm³

New volume V2 = 140 cm³3

Old temperature T1 = 143 K

Find:

New temperature T2

Computation:

V1 / T1 = V2 / T2

135 / 143 = 140 / T2

New temperature T2 = 148.3 K

New temperature T2 = 148.3 - 273

New temperature T2 = -124.7 °C
