the temperature of a balloon rises from 275 degrees k to 395 degrees k, what would the ending volume be if it started at 5 L

Airida [17]

<h3>Answer:</h3>

7.182K

<h3>Explanation:</h3>

From the question we are given;

Initial temperature, T1 = 275 K
Final temperature, T2 = 395 K
Initial volume, V1 = 5 L

We are required to calculate the final volume, V2

Charles's law is the law that relates the volume of a gas and its temperature.
It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
Therefore;

$\frac{V1}{T1}=\frac{V2}{T2}$

To calculate, V2 we rearrange the formula;

$V2=\frac{V1T2}{T1}$

$V2=\frac{(5L)(395K)}{275}$

$V2=7.182K$

Therefore, the ending volume will be 7.182K

Match each state of matter with the statement that best describes it.

Stells [14]

Answer:

State of matter is defined as a form in which matter can exist. There are four states of matter known till date. They are as follows:

Solid: Matter is said to be in solid state if it has definite shape and volume. The components of matter are closely packed and have fixed positions within the matter.

Liquid: In liquid state, matter has fixed volume but shape is not fixed, it takes the shape of container in which it is placed. The particles of liquid are close but can move freely or do not have fixed positions.

Gas: Matter in gaseous state has variable volume and shape. The particles of gas are very far from each other thus, they are in constant motion without any fixed position..

Plasma: This state of matter has variable shape and volume. It has neutral atoms, the number of ions and electrons are significant and can move freely in the matter. In order to make plasma, energy is required to strip electron from atom.

According to above definitions, the state of matter is matched with the given statements as follows:

Plasma-Particles are so hot that electrons are stripped from atoms.

Gas-It expands to fill the volume of the container.

Liquid-Particles move past each other freely but do not go fat apart.

Solid-It retains its shape regardless of the shape of the container.

Explanation:

I choose this because It understands how each plasma work.

a 0.555 g sample of mayonnase was burned in excess oxygen inside a bomb calorimeter with a total heat capacity (bomb and water)

Fofino [41]

Answer:

$Dietary\ Calories=65.6kcal$

Explanation:

Hello!

In this case, since we can see that the heat released by the combustion of the mayonnaise is absorbed by the bomb calorimeter and water, we can set up the following equation:

$m_{mayonnaise}q_{mayonnaise}=C\Delta T$
