Answer 2

What is the resulting temperature?

$here \: is \: your \: answer =$

.....................................................................

Let final temperature is T.

Then,

according to the principle of calorimetry :::::::

Heat Loss = Heat Gain

75 × 1× (100−T) = 20 ×0.5× 15 + 20× 80+ 20× 1× (T−0)

7500−75T = 150+1600+20T

95T=5750

T= 60.5∘C ≈ 60∘C

(The perfect answer will be 60.5°C I just rounded it to the nearest number for convenience, you may select either one of them according to options given :) )

Hence, the resulting temperature is 60°C

$hope \: you \: understood...$
