In the ocean, light is used by phytoplankton in order to produce sugar. 10% of the energy from the sun is available to the zooplankton that eat the phytoplankton, the rest of the energy is lost as heat or through powering body building/functions/reproduction. Whatever eats the zooplankton receives 10% of that energy in order to grow
(A) 14.8 g → 1.48 × 10^7 µg
The prefix µ means “× 10^(-6)”, so 1 µg = 1 × 10^(-6) g
The conversion factor (CF) = 1 µ g/1 × 10^(-6) g
∴ Mass = 14.8 g × [1 µg/1 × 10^(-6) g] = 1.48 × 10^7 µg
(B) 3.72 g → 3.72× 10^(-3) kg
The prefix k means “× 10^3”, so 1 kg = 1 × 10^3 g
CF = 1 kg/1 × 10^3 g
∴ Mass = 3.72 g × [1 kg/1 × 10^3 g] = 3.72× 10^(-3) kg
(C) 7.5 × 10^4 J → 75 kJ
CF = 1 kJ/1 × 10^3 J
∴ Energy = 7.5 × 10^4 J × [1 kJ/1 × 10^3 J] = 3.72× 10^(-3) kJ = 7.5 × 10^1 kJ
= 75 kJ
The temperature will be lower and the water could either become really cold or freeze. I can't exactly tell you because you're not saying if it's Celsius or Fahrenheit. <span />
