When a solid is heated , the average kinetic e energy of the substance increases because of which the temperature increases....this heat won’t affect the average kinetic energy of the substance. Since average kinetic energy will remain same during phase change , the temperature will remain same too.

Answer:
Substances which are non heat-resistant and volatile organic liquid with flammable vapor.
Explanation:
Bunsen Burner are used as a source of fire in the laboratory for heating up substances. Extra care however should be taken during heating in order to prevent fire or other forms of accidents.
Heating of mind heat resistant substances should be frowned at as the substances may get heated up and melt thereby exposing the liquid substances which may be flammable to fire thereby causing fire outbreak.
Heating of volatile organic liquid with flammable vapor should also be discouraged to prevent fire accidents.
Answer:
c. relative age
Explanation:
Relative age is a method of describing the age of rocks based on their order of appearance in the geologic column.
Events are denoted by their position in the column.
- The premise of most of the assumptions used relative age determination is based on stratigraphic laws.
- Absolute age gives numeric ages to rocks.
Since Luisa is comparing the age of people based on their position in her family, she is using the concept of relative dating.
Answer:
The chemical elements most likely to form covalent bonds are those that share electrons, such as carbon, as opposed to those that take them from another element to form an ionic bond. In general, they are nonmetals with similar electronegativities.
Explanation:
A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It's that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.
