<u>Answer:</u> The correct answer is decreasing temperature.

<u>Explanation:</u>

The relation between pressure, temperature, volume and number of moles of gas is given by the equal known as ideal gas equation:

$PV=nRT$

or,

$P=\frac{nRT}{V}$

where,

P = Pressure of the gas

V = Volume of the gas

n = Number of moles of gas

R = Gas constant

T = Temperature of gas

From the above relation, it is visible that pressure is directly related to number of moles and temperature of the gas. So, if pressure decreases, the number of moles and temperature of the gas also decreases.

Also, pressure is inversely related to volume of the gas. So, if pressure gets decreased, the volume of the gas must increase.

And, pressure is directly related to number of collisions of the particles. Thus, if the pressure decreases, this means that number of collisions between the particles must also decrease.

Hence, the correct answer is decreasing temperature.

Suppose you have a liquid solution containing two components, acetone and nonane. The boiling point of pure acetone is 56 C and

Tom [10]

Answer:

The boiling point is somewhere between 56 and 151 °C

Explanation:

Hello,

In this case, it is possible to compute it via rigorous methods in phase equilibrium by using for example a cubic equation of state to model the vapor phase and a suitable excess Gibbs free energy model for the liquid phase, nonetheless, it is an arduous task. In such a way, since the information about both acetone's and nonane's pure boiling points is given as well as acetone's mole fraction, which points out it is about a binary liquid solution, one could make up the boiling point is somewhere between 56 and 151 °C precising that it should be closer to 151 °C as the mixture is 90% nonane and 10% acetone.

Best regards.

olga_2 [115]

Answer:

C.)organs are a group of two or more different types of tissues that work together to perform a specific function

Explanation:

Cells of similar function are grouped together into tissues. For example, cardiac muscle tissue is present only in the heart, and made up of specialised cells called cardiomyocytes, or cardiac muscle cells. These cells contract to pump blood around the body.

The heart is an organ, consisting of multiple types of tissue including cardiac muscle tissue, connective tissue, blood vessels and epithelial tissue. Therefore, organs represent a group of at least two types of tissue that work together to carry out functions in the body.
