Thomas measured the pressure inside a balloon and found it was 1.25 atm. However,his lab report asked for the pressure in pascals. What was the pressure in Pa? ( 1atm=100000)

A. 1.25 X 10^5 pa
B. 2.25 X 10^5 pa
C. 1.0025 X 10^5 pa
D. 0.25 X 10^5 pa

Answer 1 is correct because 1 atm =10^5 so 1.25 atm will be equal to 1.25 *10 ^5

Answer:

[tex]A.125000Pa=1.25*10^{5}Pa[/tex]

Explanation:

1. Write down the quantity with units that you want to convert to pascals:

[tex]1.25atm[/tex]

2. Find the equivalence between pascals and atmospheres:

[tex]1 atmosphere=100000Pascals[/tex]

3. Use the conversion factor to convert the units:

[tex]1.25atm*\frac{100000Pa}{1atm}[/tex]

4. Multiply to find the result:

[tex]1.25atm*\frac{100000Pa}{1atm}=125000Pa[/tex]

5. Express the result in scientific notation:

[tex]125000Pa=1.25*10^{5}Pa[/tex]
