101.3 kPa = 1 ATM
Atmosphere is a measure of pressure, not of length like the meter.
0 C = 273.15 Kelvin 200 C = 473.15 Kelvin 1 atm/273.15 K = Xatm/473.15 K 273.15X = 473.15 X = 1.7 atmospheres of pressure ---------------------------------------------( can call it 2 atm )
ATM is the abbreviation for atmosphere's, which is a measurement of pressure. 1 ATM = 14.696 PSI 30 ATM = 440.88 PSI (440.88 pounds)/1 square inch = (40.88 pounds)/(1/144)square feet 63486.72 pounds per square foot. So 30 atmospheres is equal approximately to 63486.72 pounds per square foot.
The answer is in the question itself:760 mmHg (= 760/760 ) = 1.00 atm , so1000 mmHg = 1000/760 = 1.32 atm
