Answer:
Speed
Explanation:
Aliyah must have been trying to find her speed.
The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,
speed =
with a unit of m/s.
<em>Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed. </em>
Answer:
The volume that the same gas will occupy at 101.3 kPa if the temperature is kept constant is 5.27 L.
Explanation:
As the volume increases, the particles (atoms or molecules) of the gas take longer to reach the walls of the container and therefore collide with them less times per unit of time. This means that the pressure will be lower because it represents the frequency of collisions of the gas against the walls. In this way pressure and volume are related, determining Boyle's law that says:
"The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"
Boyle's law is expressed mathematically as:
P * V = k
Now it is possible to assume that you have a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:
P1 * V1 = P2 * V2
In this case, you have:
- P1= 92 kPa
- V1= 5.80 L
- P2= 101.3 kPa
- V2= ?
Replacing:
92 kPa* 5.80 L= 101.3 kPa* V2
and solving, you get:

V2= 5.27 L
<u><em>The volume that the same gas will occupy at 101.3 kPa if the temperature is kept constant is 5.27 L.</em></u>

Reactions like this one absorb energy because the reactants have less potential energy than the products.
<h3>What is an Endothermic reaction?</h3>
This is the type of reaction in which the reactants absorb heat energy from the surroundings to form products.
This brings about a decrease in the temperature as a result of the reactants having less potential energy than the products thereby making option B the most appropriate choice.
