The gas in the piston is being heated, and the piston has moved upward. The observation will be summarized in a row of the incomplete table below. A container with a piston inside it. An arrow above the piston points upward. Row Name Observation Variables 1 Boyle's law Volume increases when pressure decreases ? 2 Charles’s law ? ? 3 Gay-Lussac’s law ? Temperature, pressure 4 Combined gas law ? ? What are the variables for this piston? temperature only temperature and volume pressure and number of molecules volume and number of molecules.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
