Answer:

I think it's the last one.

Explanation:

Because gravity is what makes our planets stay still and stops our planets from dropping and as they orbit around the sun that's what keeps the moon from bumping into earth. I hope this helps and makes sense.

What is the pressure in atm exerted by 2.48 moles of a gas in a 250.0 mL container at 58 degrees celsius
Dvinal [7]
Since the question manages to include moles, pressure, volume, and temperature, then it is evident that in order to find the answer we will have to use the Ideal Gas Equation:  PV = nRT (where P = pressure; V = volume; n = number of moles; R = the Universal Constant [0.082 L·atm/mol·K]; and temperature.

First, in order to work out the questions, there is a need to convert the volume to Litres and the temperature to Kelvin based on the equation:
         250 mL = 0.250 L
             58 °C = 331 K

Also, based on the equation   P = nRT ÷ V

⇒         P  = (2.48 mol)(0.082 L · atm/mol · K)(331 K)  ÷  0.250 L
⇒         P  =  (67.31  L · atm) ÷ 0.250 L
⇒         P  =  269.25 atm

Thus the pressure exerted by the gas in the container is  269.25 atm.

Answer:

The pressure of the gas will  "increases by a factor of four."

Explanation:

The absolute zero in other words called as the absolute temperature. Whereas the absolute zero is the least possible temperature. In which nothing will remain cold and no heat can be released or present in the substance. When it is described in the figure it will be, –273.15 degrees Celsius on the Celsius scale. and  0 K on the Kelvin scale. This absolute temperature concept has been raised from the third law of the thermodynamics.

In a living organism, what is a tissue
Rus_ich [418]

Answer:

Tissue is a group of cells.

Explanation:

Human body tissue consists of groups of cells with a similar structure working together for a specific function.

Human body tissue is another way of describing how our cells are grouped together in a highly organized manner according to specific structure and function. These groupings of cells form tissues, which then make up organs and various parts of the body. For example, it's easy to see and feel muscle in the body. Muscle is one of the four types of human body tissue. In this lesson, learn more about the types of tissue and how each functions for a different purpose.
