If I were to hold a cube of frozen gasoline under a flame, would it combust?

We all know that gasoline freezes at temperatures around -120 degrees. Gasoline is a hydrocarbon, meaning it is composed of long chains of carbon and hydrogen. It can have anything from seven to eleven carbons per chain. We know that gasoline is flamable in its original state, but when it is frozen, it is obviously cold. It being cold is one of the things that make me think it wont catch fire.
I know that water is made when heat fuses hydrogen and oxygen. The hyrdogen in the gasoline and the oxygen in the air may fuse when under a flame causing it to melt into a liquid. Being flamable in its liquid state, it would catch fire, thus continuing to burn the cube until completely melted and burned. These are only my hypothesis. Tell me what you think.

Ammonia is an inorganic compound and not a fuel. It is a noncarbonious material. It combines with air and forms explsive mixture when the composition of ammonia in air is between 16 and 25%. Ammonia is in vapour form at 1 atmospheric pressure and temperature above minus 33 degree celcius.

7 parts olive oil
6 parts sea salt (or kosher salt, or any coarse salt)
5 parts lemon oil
4 parts baking soda
3 parts rosemary oil
2 parts eucalyptus globulus oil
1 part vitamin E oil (tocopherol)

Mix together in bowl and stir rapidly so oils don't disolve salts. Then spread salt rocks smoothly over cooky sheet and let dry a little. Or, if you don't mind the oil, immediately transfer to storage container.

Can someone show me step by step how to work this problem:
The heat of fusion of water is 80 cal/g, the heat of vaporization of water is 540 cal/g, the specific heat of ice is .48 cal/deg/g, the specific heat of steam is .48 cal/deg/g, and the specific heat of liquid water is 1.0 cal/deg/g. How much heat would be needed to convert 12.37 g of ice at -35 degrees C to steam at 146 degrees C.
