Express your answer in degrees Celsius to three significant figures i ) that is filled with olive oil 1 ) to a height of 1.30 mm below = 2.7 × 10 s (Co) -6.8 × 10 4 (C" ) the top of the cup. Initially, the cup and oil are at a kitchen temperature of 21.5 C. You get a phone call and forget about the olive oil, which you inadvertently leave on the hot stove. The cup and oil heat up slowly and have a common temperature eC Submit

Explanation / Answer

Expansion of oil is more than that of the glass.
Area of expansion for both the glass and oil is the same.
Hence the difference in increase in heights of oil and glass for a rise of temperature °C
{(10.6-0.13) 6.8e-4 - 10.5*2.7e-5}* = 0.13 cm
Solving we get = 19.016° C
Final temperature is 21.5 + 19.016= 40.516° C ................Ans.
