Aballoon that had a volume of 3.5 l at 25.0 c is placed in a hot room at 40.9 c. if the pressure remains constant at 1.00 atm, what is the new volume of the balloon in the room?

V1/T1 = V2/T2

V1= 3.5 L

T1 = 25 +273=298 K

T2 = 40.9 + 273 = 313.9 K

V2- ?

3.5 L/298 K= V2/ 313.9 K

V2 = (3.5 L*313.9 K)/298 K ≈ 3.69 L

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
