Answer: The molecules in gases are different from other states of matter
Explanation:
The molecules in gases are different from other states of matter because unlike, for example, a solid, they move around freely and are much more spread apart. A gas can fill up any container, but once the container is unsealed, the gasses will immedietly be let out. Gases can be compressed much more easily than a solid or a liquid.
Answer:
KE = 1/2mv^2
KE = 1/2(24)(3^2)
KE = 12(9)
KE = 108 J

with more mouths to feed, you need more food, but when your food doesn't increase with your population, then there is a food shortage.
Answer:
Q = 41800[J]
Explanation:
These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.
where:
Q = Heat absorbed [J]
m = mass = 2 [kg]
DT = temperature change = 5 [°C]
Cp = specific heat of the water = 4180 [J/kg*°C]
Units of energy (Joules) [J]
