Increasing the temperature of a gas sample means that heat energy is been supplied to the System. When energy is been supplied heat energy is transformed into kinetic energy of the gas molecules.
Therefore kelvin temperature increases means more energy given to the system therefore average kinetic energy of molecules increase.
When the kinetic energy of molecules increase they move about more and take up more space. Hence volume too increases.
Therefore the correct answer is
4) average kinetic energy of molecules increase and volume of the gas sample increases
Answer:
freezing
Explanation:
The process in which a liquid changes to a solid is called freezing or solidification. Energy is taken away during freezing.
A.) Cesium is the lowest electronegative element......
Answer:
2Mg + O2 = 2MgO
Explanation:
Al + 3F2 = AlF3 ..... F has 6 on the left and 3 on the right.
Na + F2 = 2NaF ..... Na has 1 on the left and 2 on the right.
2Al + 3O2 = Al2O3 .... O has 6 on the left and 3 on right.
Gases and plasma's undergo changes in volume most easily<span>. In contrast, liquids and solids have fixed volumes, although liquids do not have fixed shapes. Gases and plasma's expand or contract to fill their containers.</span><span />
