Question 1
Density and UpthrustThe density of 400 cm3 of palm oil was 0.9 g cm−3 before frying. If the density of the oil was 0.6 g cm−3 after frying, assuming no loss of oil due to spilling, its new volume was
- A.360 cm3
- B.600 cm3
- C.240 cm3
- D.800 cm3
- E.450 cm3.
Show the answer and explanation
Answer: B (600 cm3)
Explanation
The mass does not change: 0.9 × 400 = 360 g. New volume = mass ÷ new density = 360 ÷ 0.6 = 600 cm3.
