turn 0 C to 273 K , 30 C to 303K then 255*85/303=101.3*V/273 V=193mL
Mercury -39C Gallium 30C
1 mol N2 = 28g 30C = 303K At STP, 1mol * 273K is proportional 24L * 760torr. (PV = nRT) Then we do a little bit of stoichiometry... 10g * 1mol/28g * 24L*760torr/(1mol*273K) * 303K * xL/750torr = 9.6402 L 10.0g of N2 at 30C and 750torr should occupy 9.6402L
The speed of sound in air at 30C is approximately 349 m/s. To calculate the time it takes for sound to travel 33.1 m, you divide the distance by the speed of sound: 33.1 m / 349 m/s ≈ 0.095 seconds.
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
86 °FTo convert from °C to °F you use the formula °F = (9/5)x(°C) +32That means 30 °C converts to:9x30/5 + 32 = 9x6 +32 = 54 +32 = 86 °F
It is the same overall volume, but a different shape. A 30C will have a narrower chest that protrudes more, while a 34A has a broader chest and protrudes less. When you move down a band size, you move up a cup size to maintain the same overall volume. 34A = 32B = 30C.
A) more than 30c B) at or about 30c C) less than 30c The correct answer is A) more than 30c
Elemental sulphur is a solid at 30c
Try it, 30c would be a good asking price.
-30c
90a
2 but you would have 30c left
A dollar is 100c and so there are three 30c in it with a remainder of 10c
