<u>Answer:</u>
<em>To relate the type of box material to the warmth inside the box
</em>
<u>Explanation:</u>
3 boxes are made with three different materials glass, plastic and Aluminium. Thermal conductivity is different for different materials. thermal conductors allow easy flow of heat through them and insulators allow minimal or no flow of heat through them.
Thus the amount by which an object gets heated up depends on the value of its conductivity. In this experiment, glass and plastic are insulators and aluminium is a conductor. Among glass and plastic, plastic is a better insulator.
<em>Thus the heat contained in the boxes will be of the order </em>Aluminium>glass>plastic.
To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.
Answer:
A boiler is a type of coal fired power plant.
Explanation:
The correct answer should be kinetic molecular velocity. Which is a
complex term for the speed of molecules. The faster the molecules move
the more liquid the chemical will be, with the fastest being gaseous
molecules. The slowest ones are things that are solid. This is easily
observed on water that is slowest when ice and fastest when water vapor.
