Why is a sample of radioactive material always a little warmer than its surroundings?
Radioactive material is warmer than the surrounding material because radioactive material is constantly breaking down. When material breaks down, that means that energy is constantly getting released. When energy is released, it produces warmth.
When propane reacts with oxygen does the surroundings area become warmer or cooler?
warmer
If a gas condenses to liquid will it make its surroundings warmer or cooler?
Much warmer.
What will an object that is warmer then its surroundings do?
In that case, heat energy will tend to flow from that object to its surroundings.
What will happen to a radioactive material when it is heated and at what point will it burn out completely?
Just like any other material, it gets warmer, most likely expands, and may transition from solid to liquid and/or from liquid to gas. If it's already in the gaseous state, then its pressure increases. Its rate of radioactive decay is not affected.
What will an object that is warmer than it's surroundings do?
cool down to the temperature of its surroundings slowly
What happens to the air in the surroundings as warm as rises?
It gets warmer.
What happen to air in the surroundings as warm air rises?
it gets warmer as it rises
What happened to the air in the surroundings as warm air rises?
it gets warmer as it rises
What is localized convective lifting?
When warmer air rises so when a localized surface is warmer than its surroundings, the air above that surface is warmer and will also rise. This also makes clouds.
An object is warmer than its surroundings it will?
Release its heat energy until the object (system) and the surroundings are the same temperature.
What kind of energy transfer takes place when your coffee gets cold?
Heat from the coffee goes to the surroundings. The coffee gets colder, the surroundings get warmer.
