Answer:
P2 = 128,205 pascal.
Explanation:
<u>Given the following data;</u>
Original Pressure, P1 = 100,000 pascals
Original Temperature, T1 = 273K
New Temperature, T2 = 350K
To find new pressure P2, we would use Gay Lussac' law.
<em>Gay Lussac's law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas. </em>
Mathematically, Gay Lussac's law is given by;
Where;
- P represents pressure.
- T represents temperature.
- K is the constant of proportionality.
<em>Making P2 as the subject formula, we have;</em>
Substituting into the equation, we have;
P2 = 128205.13 ≈ 128205 pascal.
<em>Therefore, the pressure inside the hot water bottle is 128,205 pascal. </em>
Answer:
millisecond
Explanation:
Time is measured in seconds in the SI system. The scientist will measure the time it takes to complete one flap of the wings. In the SI system the use of prefix makes it easier to describe the value. It is as follows
Here, the wings flap so fast that the millisecond should be used.
