Answer:
Hello I recently learned inertia so I hope this helps. :))
Do great
1. 1kg I say this because inertia stands for less movement.
2. 5kg because imagine a 5kg ball falling from the sky wouldn't the heavier object speed up faster.
3. A heavier hammer would cause gravity to pull which means it would add more force to it than a light weight toy.
Answer:
The balloon will instanly freeze and "shatter" :)
Explanation:
The volume of a gas will shrink if its temperature decreases. The cold liquid nitrogen cools the air inside the balloon. As a result the molecules of air slow down causing the volume of the balloon to decrease. :)
Have an amazing day!!

Answer:
Explanation:
Total pressure = partial pressure of nitrogen + partial pressure of water vapour
partial pressure of water vapour = 18.7 mm of Hg
760 mm of Hg = 1 atm
18.7 mm of Hg = 18.7 / 760 atm
= .0246 atm
Total pressure = partial pressure of nitrogen + partial pressure of water vapour
Putting in the values in atm
1.72 atm = partial pressure of nitrogen + .0246 atm
partial pressure of nitrogen = 1.72 atm - .0246 atm
= 1.6954 atm
= 1.70 atm
partial pressure of nitrogen = 1.70 atm .
Answer:
Partial pressure of oxygen = 190 mmHg
Explanation:
From the question;
Mixture contains only nitrogen and oxygen
Total pressure of the mixture = 480 mmHg
Partial pressure of nitrogen = 290 mmHg
Dalton's law states that the pressure of a system is as a result of the sum of the partial pressures of the individual components of the mixture. This means that in this mixture;
Pressure of mixture = Partial Pressure of Nitrogen + Partial Pressure of Oxygen
480 = 290 + Partial pressure of oxygen
Partial pressure of oxygen = 480 - 290
Partial pressure of oxygen = 190 mmHg
