Question

Calculate the increase in volume of a liquid when heated through 40°C. Given
that original volume of the liquid is 2 litres and its volume expansion coefficient is
12 x 10^-4\°C.​

Answer 1

Explanation:

Thank you for free points

40° + 40°

= 80°

80 x 10

= 90°

I hope it may help to

Answer 2

$∆v ={?} \\ ∆t = 40° \: C \\ v = 2 \: litres \\ \gamma = \frac{∆v}{v \times ∆t} \\ 12 \times {10}^{ - 4} \times 2 \times {10}^{ - 3} \times 40 \\ 96 \times {10}^{ - 7} \: or \: 960 \: ml$
