Answer:
Increase the pressure of the gas
Explanation:
According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).
From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.
When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.

Can someone help me find the 5 digits numbers in here?
Answer:
20322
Explanation:
A student finds a rock on the way to school. In the laboratory he determines that the volume of the rock by placing the rock in a graduated cylinder with 50 mL of water and watched the water rise to 72.7 mL. The student determined the mass is 39.943 g through the use of a triple beam balance. What is the density of the rock?
Answer:
1.76 g/mL
Explanation:
You need to find the volume. You can do this by subtracting the volume of the water and the rock by the volume of the water.
72.7 mL - 50 mL = 22.7 mL
Now that you have volume, divide the mass by the volume to find the density.
39.943 g/22.7 mL = 1.76 g/mL
What is the melting point of the above substance?
Which of the three sub-atomic particles is the lightest?
a The proton
b The neutron
c The electron
d orbital
Answer:
The electron
Explanation:
The electron will be the lightest subatomic particle.
Answer:
The electron
Explanation:
Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.10938356 × 10 −31 kg, which is only 1/1,836 the mass of a proton.
What is the density of a rectangle solid with dimensions
of 15 cm x 25 cm x 5 cm and has a mass of 3000 g?
Answer:
5625000gm/cm^3
Explanation:
volume=w*h*l=25*15*5=1875cm^3
density=mass*volume
=1875*3000
=5625000gm/cm^3

where are the electrons found in Bohrs atomic model
Answer:
Explanation
In the Bohr model of the atom, electrons travel in defined circular orbits around the nucleus. The orbits are labeled by an integer, the quantum number n. Electrons can jump from one orbit to another by emitting or absorbing energy.
Oxygen and silicon makes up what percentage of the Earth crust.
A) 57% B) 98.5% C) 75% D) 50%
answer
the answer is C
explanation
this is because the oxygen makes up 46.1%of the earth's surface while silcon is 28.5% and the question says "what makes up" which means you should add them and it becomes 74.6% which Is approximately 75%

cubic centimeter (cm^3) has the same volume as a
Answer:
1 cc=1 ml=0.001 liter
Explanation:
One cubic centimeter has the same volume as one milliliters. Both are equally used in analytical problems to express the volume of a substance.
What is volume ?Volume is a physical quantity that measures the total space occupied by a substance. Volume is an extensive quantity and thus depends on the amount of the substance.
The mass of a substance per unit volume is called its density. Volume is dependent on the intermolecular forces between the particles of the substance. The SI unit of volume is liter (L). Other units are ml, cm³, dm³ etc.
One cubic centimeter has the volume as one milliliters.
Hence, 1 cm³ = 1 ml
1000 m or 1000 cm³ is one liter of the substance.

Green light has a frequency of 6.01 x 1024 Hz. What is the wavelength?
Answer:
λ= 4.99 * 10^-17
Explanation:
C= F * λ
F= frequency(Hz)
λ= wavelength(m)
C= 3.0 * 10^8

A mechanical pencil has a mass of 47.4 grams. The volume of the pencil is 15.8 cubic centimeters. What is the density of the pencil?
Answer:
3 g/cm^3
Explanation:
Density can be determined by mass divided by volume, or P=m/V.
This would be 47.4 grams (mass) / 15.8 cubic centimeters (volume). The units are grams per cubic centimeter, noted as g/cm^3.
