Answer:
The beach ball will get larger at the beach because the molecules are moving faster.
Explanation:
We can answer this problem by using Charle's Law, which states that:
"For a constant mass of an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its temperature"
Mathematically:
where
V is the volume of the gas
T is the absolute temperature of the gas
Here, we are analyzing the air inside the ball (the gas). We are also told that when the ball is brought to the beach, the pressure does not change: therefore, we can apply Charle's Law.
We are told that when the ball is brought to the beach, the temperature increases from 18℃ to 32℃: therefore, since the volume of the air (and the ball) is proportional to the temperature, this means that the volume of the ball will increase as well.
The reason for this is that the ball is not thermally isolated, so the molecules of the air inside the ball reach soon the same temperature of the surroundings, and so they will move faster (higher temperature means higher average kinetic energy of the molecules, so the molecules move faster, and therefore the ball will expand).
So the correct option is
The beach ball will get larger at the beach because the molecules are moving faster.
Answer:
The correct statements are :b, c , d, and e.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the equilibrium quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
, reaction will move in forward direction and concentration of products will increase.
, reaction will move in backward direction and concentration of reactant will increase.
reaction is at equilibrium.
