A 4.0 g sample of iron was heated from 0°C to 20.°C. It absorbed 35.2 J of energy as heat.
What is the specific heat of this piece of iron?

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck

B? i feel like this is a trick  

Depends on the speed of the car.
