A pupil wanted to investigate what the specific heat capacity of orange juice was.

They measured the temperature of their 250 mL glass of orange juice and recorded the temperature as 25 °C and then began heating the glass. When they stopped recording at 35 °C, 9.73 kJ of energy had been absorbed by the orange juice.

Use this information to calculate the specific heat capacity of orange juice.

(a)  

A scientist conducted an experiment to investigate how much heat energy in kJ would be required to heat 500 mL of methanol by 30 °C. The specific heat capacity of methanol is 2.53 kJ kg⁻¹ °C⁻¹.

Use this information to calculate how much heat energy would be required.

(a)  

100 mL of water was heated with 60 kJ of heat energy. What temperature change would this have caused?

Specific heat capacity of water is ~4.2 kJ/kg°C

Round your answer to 3 significant figures.

(a)  

30g of water was heated and its temperature was raised by 12°C. Calculate how much heat energy was supplied to the water during this time.

The specific heat capacity of water is 4200 J/kg°C

(a)  

The specific heat capacity of marble is 832 J/kg°C. If a 700 gram block of marble was heated by 34°C, how much heat energy would have been required to do this?

Do not round your answer.

(a)  

A typical nuclear bomb requires ~15 grams of uranium to be operational. Calculate the change in temperature at the centre of a nuclear explosion if the bomb provided 172, 500 kJ of energy to the uranium and the specific heat capacity of uranium is 115 J/kg/°C.

Do not include commas in your answer

(a)  

A student set up an experiment similar to the one shown to investigate the specific heat capacity of a 2500 gram block of rubber. The block was supplied with 250.625 kJ of energy which caused the temperature of the block to rise by 50 °C.

Calculate the specific heat capacity of rubber in J/kg°C.

(a)  

A student set up an experiment similar to the one shown to investigate the specific heat capacity of a block of rubber. The block was supplied with 104356 J of energy which caused the temperature of the block to rise by 27 °C. The specific heat capacity of rubber is 2005 J/kg°C.

Use this information to calculate the mass of the block of rubber. Give your answer to two decimal places.

(a)  

If the sun provided 15000 J of heat energy to a 1kg block of concrete, how much would the temperature of the block increase by? (ignoring loss of heat to the environment). The specific heat capacity of concrete is 829 J/kg°C.

Give your answer to two decimal places.

(a)  

The helium in a balloon had a mass of 11 grams. If the helium was heated by 7 °C with 400 J of energy, what would the specific heat capacity of helium be?

Give your answer to 2 decimal places.

(a)  

A gold bar was given 18,000 Joules of heat energy and the temperature increased from 25 to 95 °C as a result. The specific heat capacity of gold is 130 J/kg°C.

Calculate the mass of the gold bar.
