Answer:
False
Explanation:
A food chain shows what eats what but a food web shows all of the different paths of what eats what and what ate what.
Answer: Two elements are liquid at standard temperature and pressure: mercury and bromine. All the other elements are solid under standard conditions, which means their freezing point is above 0 degrees Celsius. Hope this helps (:
the conversion of liquid to vapours is a change in state of a system from one state to other
there are basic two differences between three states of matter
1. thermal energy: gas has highest thermal energy tthen liquid and least us of solids
2. intermolecular forces of attractions
solids have highest intermolecular forces of attraction , then liquid and least in gas
sovas we increase the temperature the forces if attraction decrease s and thermal energy increases.
So when we heat liquid more moleculws gets energised attaining thermal motion in the range of gas thus the rate if evaporation increases.

Answer:</h3>
9,729.73 L
<h3>
Explanation:</h3>
- Based on Boyle's law when temperature is held constant then the volume of a fixed mass of a gas, V is inversely proportional to Pressure, P.
- That is; Pα 1/V
- Mathematically, P= k/V where k is a constant
- Therefore, when the volume of a gas and the pressure are altered,
- P1V1=P2V2 = k, where P1 and P2 are the initial and final pressure respectively while V1 and V2 are the initial and final pressure respectively.
In this case;
Initial Pressure, P1 = 150 atm
Initial volume, V1 = 60.0 L
Final pressure, P2 = 0.925 atm
we are required to calculate the final volume
But, P1V1 =P2V2
Rearranging the formula, V2 = P1V1 ÷ P2
Thus;
V2 =(150 atm × 60.0 L) ÷ 0.925 atm
= 9,729.73 L
The new volume will be 9,729.73 L
