When the volume of a gas is changed from 250 ml to 425 ml, the temperature will change from 137 c to

When the volume of a gas is changed from 250 mL to 425 mL, the temperature will change from 137° C. What is temperature 2? Using Charles law

T2=697K

Explanation:

Set up the formula and identify data as provided in the problem. 

V1T2=V2T1
where:

V1=250ml
V2=425ml
T1=137oC
T2=?−

Make sure to convert 137oC→K. This is the most important point to remember because the volume of a fixed mass of a given gas is directly proportional to the temperature expressed in K; not C; i.e.,
137oC→?−K
K=⋅oC+273
K=137+273=410

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.
