2*8 = 16
4*1 = 4
16-4 = 12
Answer:
23 Pa
Step-by-step explanation:
According to ideal gas law, PV = nRT. If V is constant, then:
P/T = P/T
Remember that P and T are absolute. So °F must be converted to either Rankine or Kelvin.
To convert °F to Rankine, add 459.67.
30°F + 459.67 = 489.67 R
80°F + 459.67 = 539.67 R
21 Pa / 489.67 R = P / 539.67 R
P = 23.1 Pa
Rounded to two significant figures, the pressure is 23 Pa.
Answer: 17/20
Step-by-step explanation:
0.85 = 85/100 = 17/20
The number 0.85 can be written using the fraction 85/100 which is equal to 17/20 when reduced to lowest terms.
Answer:
