Question 1

1. How many joules of heat are required to heat 692 g of nickel from 22°C to 318°C?
The specific heat of nickel = 0.440 J/goC (Round to the nearest whole number in your answer and include units)

Question 2

An unknown metal with mass 6.05 g is heated to 90.00°C and dropped into 11.0 g of water at 23.00°C. The final temperature of the system is 23.83°C. What is the specific heat of the metal? Assume the specific heat of water is 4.184 J/g oC. (Round to 4 decimals and include units)

Question 3

The higher the specific heat of an object,

the quicker an object will increase in temperature 

the more energy released as it decreases in temperature.

the weaker the intermolecular attractions are in the object.

the greater the change in temperature when calculating heat.

Question 4

When a hot object comes into contact with a cold object, it is always true that...

change in temperature of the hot object is greater than the change in temperature of the cold object.

the amount of heat gained by the cold object is the same as the amount of heat lost by the hot object.

the initial temperature of the hot object equals the initial temperature of the cold object.

Question 5

Temperature is the measure of total kinetic energy in all the particles in a substance.

True

False

Question 6

Calculate the specific heat of an unknown metal if 342.0 g of the metal, warmed from 21.3°C to 46.3°C absorbs 291.7 J of heat.
