The temperature between your morning jog and your lunch at noon increases from 4

Question

The temperature between your morning jog and your lunch at noon increases from 43.1 degreeF. The corresponding change of temperature in Celsius scale is closest to: 10.6 Cdegree 1.18 Cdegree 13.9 Cdegree 15.7 Cdegree 17.8 Cdegree A copper (beta = 51 times 10^-6/Cdegree) flask with a volume of150 cm^3 is filled to the brim with olive oil (beta = 680 times 10^6/Cdegree) at 9.0 degree C. If the temperature changes from 9.0 degree C to 24 degree C, the volume of olive oil that is spilled from flask is closest to: 1.1 cm^3 1.7 cm^3 1.4 cm^3 2.3 cm^3 2.0 cm^3 A block of metal (specific heat c = 390 J/kg.Cdegree) with an initial temperature of 30 degree C is dropped holding 2.2 kg of water (specific heat c = 4,186 J/kg.Cdegree) at 20 degree C. If the final equilibrium temperature and water system is 20.3degree C, the mass of the metal block is closest to: 0.50 kg 0.73 kg 1.0 kg 1.3 kg

Explanation / Answer

Temperature difference,

Delta_T = 75.2 - 43.1 = 32.1 F

= [(75.2-32)5/9] -  [(75.2-32)5/9]

= 5/9* 32.1

= 17.833 degree celcious.
