If temperature t is directly proportional to heat h, and when t = 20oC, h = 50 J, find t when h = 60J.... Question 26315

If temperature t is directly proportional to heat h, and when t = 20^oC, h = 50 J, find t when h = 60J

24^oC

20^oC

34^oC

30^oC

Correct answer is A

t ∝ h, t = 20, h

t = ? h = 60

t = kh where k is constant

20 = 50k

k = \(\frac{20}{50}\)

k = \(\frac{2}{5}\)

when h = 60, t = ?

t = \(\frac{2}{5}\) × 60

t = 24^oC
