Answer 1

Hey dear,

We take temperature constant during ohms law experiment because the matter will expand or shrink.
perfectly definitely pure correct answer.

Answer 2

We take temperature constant during the ohm's law so as to keep the law valid. If temperature change s then resistance in the resistor also changes, and hence resistance will not be constant, making ohm's law (.i. e V=IR) Invalid.
