Explanation:
When we have to convert temperature from degree celsius to kelvin then we add 273 into the given degree celsius temperature.
Therefore, convert into kelvin as follows.
Temperature in kelvin = Temperature in degree celsius + 273
= (32.5 + 273) K
= 305.5 K
Thus, we can conclude that temperature in kelvins is 305.5 K.

43.7 °C
Explanation:
= Coefficient of linear expansion of brass =
= Coefficient of linear expansion of steel =
= Initial length of brass = 31 cm
= Initial length of steel = 11 m
= Total change in length = 3 mm
Total change in length would be
The final temperature is 43.7 °C
Answer:
a. The thickness of the wire is 2.5 mm.
b. The wire is 0.25 cm thick.
Explanation:
Number of turns of the wire = 10
The length of total turns = 25 mm
a. The thickness of the wire can be determined by;
thickness of the wire =
=
= 2.5 mm
Therefore, the wire is 2.5 mm thick.
b. To determine the thickness of the wire in centimetre;
10 mm = 1 cm
So that,
2.5 mm = x
x =
= 0.25 cm
The wire is 0.25 cm thick.
