Answer:- Volume decreases by a factor of 1.15.
Solution:- At constant pressure, volume of the gas is directly proportional to the the kelvin temperature.
The equation is written as:
where, 
is the volume at initial temperature 
and 
is the volume at final temperature 
.
Temperature must be in kelvins. So, let's convert both the temperatures to kelvin.
To convert degree C to kelvin we add 273.
So, = 100 + 273 = 373 K
= 50 + 273 = 323 K
The equation could also be written as:-
= 1.15
From here we could say that the volume decreases by a factor of 1.15.
For example if the initial volume is 1 L then final volume will be 
that is 0.87 L.
Answer:
Iron, copper , calcium
Explanation:
Iron , copper and calcium are present in three different groups.
Iron is present in group eight.
Copper is present in group eleven.
Calcium is present in group two.
Sodium , potassium and rubidium are present in same group i.e. group one. These are alkali metals.
Fluorine, chlorine and bromine are present in group seventeen. These are halogens.
Argon, Krypton and xenon are present in same group i.e, group eighteen. All are these noble gases.
There is a thing called gravity. Gravity in the earth causes anything to stay down. There was an experiment a person held a plastic box with bricks on earth. It was really hard to pick it up. Then in the ISS (International Space Station) the same person help and it was so much easier no hardship at all, even a baby can do it!!
