For A pressure of 25.7 inHg would be how many kilopascals? I did the following, is this correct? 25.7 inHg X 25.4 mm/1in X 101.325 KaPa/760 mmHg = 87.0301 Kapa So: KaPa = 87.0

For A pressure of 25.7 inHg would be how many kilopascals? This is the answer I received: 25.7 mmHg x (101.325 kPa/760.0 mmHg) The mmHg cancel each other out So 98.659 kPa My Question is I started out with inHg, and not mmHg. Would it be the same since I'm starting with in...

how to solve for a 28.4 L sample of methane gas is heated from 35.0° C to 76.0° C. The initial pressure of the gas is 1.00 atm at 35.0° C. Assuming constant volume, what is the final pressure of the gas? OK, I did the following: P₁ = 28.4 L P₂ = ? TS...

Consider a roller coaster as it travels near the bottom of its track as sketched in the figure below. At this point, the normal force on the roller coaster is three times its weight. If the speed of the roller coaster is 27 m/s, what is the radius of curvature of the track? I ...

In the figure below, m1 = 9.5 kg and m2 = 4.0 kg. The coefficient of static friction between m1 and the horizontal surface is 0.60 while the coefficient of kinetic friction is 0.30.

What is an expanded algorithm? Son doesn't know and didn't bring home his textbook, any ideas?
