The answer is No. That is the mass of the sealed jar and its contents does not change upon the vaporization of the liquid, as according to the “law of conservation of mass” , the mass remain conserved when no matter is escape, the mass will remain constant and here also as the jar is sealed, no matter is escaped thus no mass change will be there.
Answer:
solid matter is composed of tightly packed particles. A solid when we retain its shape the particles are not free to move around. liquid matter is made of more Loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained. gaseous matter is composed of particles packed so loosely that it is neither a defined shape nor a Define volume. A gas can be compressed
Answer:
I think that gravity can be considered a force.
Explanation:
As the object falls, it moves faster and faster. Gravity is considered a universal force because it acts between any two masses anywhere in the universe. For example, there is a gravitational pull between the Sun and the Moon. Even small masses attract one another.
Hope this helped! :)
Answer:
the volume of the hydrogen sample is greater than the volume of the helium sample.
Explanation:
Density=mass/volume
Now just plug each value in the given equation
For Helium
0.00018 g/cm3 = 1g/x
x= 5555.56 cm3
For hydrogen
0.00009gcm3=1g/x
x= 11111.11 cm3
This shows us that the volume of the hydrogen sample is greater than the volume of the helium sample.
I think this is correct but double check my work and ask others as well!
The answer is 1 3 and 5 just took the test !!!!
