Answer:
Increases
Explanation:
We will use Charles law for solving this type of question
V1/T1=V2/T2
Note= first change the degree to k i.e. 20+273= 293k
Lets suppose we say that the temperature is increased by 10o
The new temperature is, 303k
Convert the volume in dm3= 25/1000 = 0.025 dm3
Now put the values in Charles law
V1/T1=V2/T2
0.025/293 = v2/303
303 x 0.025 / 293 = v2
0.026 dm3 =v2
Or
0.026 x 1000 = 26 cm3
