Answer:
P₂ = 1.92 atm
Explanation:
According to the boyle's law:
The pressure of given amount of gas at constant temperature and number of moles of gas is inversely proportional to the volume.
P₁V₁= P₂V₂
Given data:
Initial volume = 4.00 L
Initial pressure = 1.20 atm
Final volume = 2500 mL
Final pressure = ?
Solution:
First of all we will convert the volume into litter.
2500 mL × 1L/1000 mL = 2.5 L
P₁V₁ = P₂V₂
P₂ = P₁V₁ /V₂
1.20 atm×4.00 L = P₂ ×2.5 L
P₂ = 1.20 atm×4.00 L/ 2.5 L
P₂ = 4.8 atm. L/ 2.5 L
P₂ = 1.92 atm
Answer:
the heat flows from the hand to the ice cream
Explanation:
we produce body heat therefore it moves to the ice cream also there is no possible way the heat could move from the ice cream because the ice cream is cold
Answer:
Answer: Change in speed = 11 m/sTime taken = 3.4sHence, acceleration = (11/3.4) m/s² = 3.235 m/s²

A scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of the phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research
