Metallic substances have higher specific heat capacities than nonmetallic substances?
yes metallic substances have higher specific heat capacities
What is the Difference between heat labile and heat stable substances?
Heat labile substances are destroyed or corrupted by heat, for example many proteins lose their structure (unfold) at temperatures considerably lower than boiling point. Heat stable substances maintain form and function at higher temperatures. Heat stable/labile properties are often used in biochemistry to distinguish organic molecules such as enzymes, cell proteins and toxins.
Thermal conductors are substances that do what?
They are good and conducting and transferring heat.
Why should the air hole be open when you heat substances with the Bunsen burner?
If the air hole is closed, no air is getting to the flame. Fire must have oxygen in order to burn.
Heat transfer between two substances that are in contact is called what?
CONDUCTION
How are coal and oil types of energy?
They are not. They are substances which are sources of energy. When you burn them chemical energy is changed to heat and light.
What is a Bunsen burner placed on?
It should be placed on a Safety Heat Proof Mat on to a gauze and then on to a tripod.
What are the four sources of heat?
what are the four sources of heat
Metallic substances have higher specific heat capacities than nonmetallic substances?
yes metallic substances have higher specific heat capacities
What are the sources of internal heat?
Main sources of internal heat are Magmatism and Radioactivity.
Should heating vents be placed near the floor or near the ceiling of the room?
Heating vents should be placed near or on the floor in a room because heat travels up not down.
What heat sources causes burns?
All heat sources. Plus extreme cold sources cause burns.
What are heat conductors and heat insulators?
the substances that allow heat to pass through them easily are called heat conductors. the substances that do not allow heat to pass through them easily are called heat insulators. ruchi
Does the difference in the level of heat between two substances determine the heat transfer rate between the substances?
true
Are all heat sources are light sources?
no
What can serve as modes of both heat gain and heat loss from the body?
There are two sources by which heat is produced in our body.Endogenous sources and Exogenous sources.Endogenous sources heat by our metabolic and muscle activity. Exogenous sources heat when the environmental temperature exceeds our body temperature and that is transferred to our body.
Why should heating vents be placed on the floor?
Heating vents should be placed on or near the floor because heat rises. In rising, it will warm the air of the room. If the heating vent were near the ceiling, the room would stay chilly, even though heat was being poured into it.
