Charles's law states that A-Volume decreases as pressure decreases
B-Volume decreases as temperature increases
C- Pressure and temperature are inversely proportional
D- Volume increases as temperature increases

Answers


A modern statement of Charles's law is:  Whenthe pressure on a sample
of a dry gas is held constant, the Kelvintemperature and the volume will be
directly related.

Choice 'D' looks like the closest one.


While I was answering this question, I discovered something very useful:

me everything I wanted to know about it, and a lot more.  You could try it.

The amount of silica in the magma and temperature are factors that determine the viscosity of magma.

Answers

The viscosity of magma increases as the silica content increases from basalt to rhyolite.

A sample of aluminum metal absorbs 8.32 J of heat, upon which the temperature of the sample increases from 23.2 degrees C to 30.5 degrees C. Since the specific heat capacity of aluminum is 0.90 J/g-K, the mass of the sample is what in grams?

Answers

Given:

8.32 J of heat

from 23.2 degrees C to 30.5 degrees C

heat capacity of aluminum is 0.90 J/g-K

 

Required:

m in grams

 

Solution:

H = mCpT

(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K

m = 1.27g

Which sequence describes the result of increasing the number of gas particles in a container? A.) fewer collisions --> lower collision force --> lower pressure B.)more collisions --> lower collision force --> lower pressure. C.) fewer collisions --> greater collision force -->higher pressure. D.)more collisions --> greater collision force --> higher pressure

Answers

Answer: Option (D) is the correct answer.

Explanation:

It is known that relation between pressure and force is that, pressure equals force divided by area.

Mathematically,      P = (F)/(a)

where              P = pressure

                        F = force

                        a = area

Hence, when there is increase in number of gas particles in a container the there will be more number of collisions due to increase in number of particles. This will lead to greater collision force and as a result there will be increase in pressure because force is directly proportional to pressure.

Thus, we can conclude that the sequence more collisions --> greater collision force --> higher pressure best describes the result of increasing the number of gas particles in a container best describes the result of increasing the number of gas particles in a container.
I believe the correct response is D. More collisions that result in greater collision force and higher pressure.
