What factor is mostly responsible for the form of matter?
temperature
pressure
weather
time

Temperature because it determines how quickly the molecules move, hence determing the state of matter.

Step-by-step explanation:

Both temperature and air pressure affect the form of matter. However, temperature contributes more to the form of matter.

By raising the temperature, you're adding energy. This energy gives the individual molecules/atoms the ability to overcome the forces that hold them together. This can be seen with a solid to a liquid or a liquid to a gas.  

On the other hand, y lowering the temperature, you're removing energy. The lack of energy results in less movement. Gases condense into liquid because they don't have enough energy to stay away from each other. Liquids solidify because they don't have enough energy to slide past each other; they get stuck in place.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
