Answer:
Q = 31798.4J = 31.79kJ
Explanation:
Heat energy (Q) = ?
Mass (m) = 152g
T1 = 24°C
T2 = 74°C
Specific heat capacity of water (c) = 4.184J/g°C
Q = Mc∇T
Q = 152 * 4.184 * (74 - 24)
Q = 635.968 * 50
Q = 31798.4J
Q = 31.79kJ
Heat required is 31.79kJ

What did whales look like million years ago?
It lived in or near estuaries about 50 to 48 million years ago. Like Pakicetus, it spent time both in and out of water, but its large feet looked more like flippers than its ancestor's longer legs. ... This five-metre-long animal had proper flippers and tiny hind legs.
Given the equation N=O/P, solve for P by multiplying the left and right by P/N:
N * P/N = O/P * P/N
P = O/N
