Answer:
Higher pH (more alkaline)
Explanation:
The pH scale measures on a scale of 0 to 14 the acidity or basicness of whatever is being tested.
The lower the pH, the more acidic it will be. Acids are scaled as being anything having a pH of lower than 7.
The higher the pH, the more alkaline (or basic) it will be. Bases are scaled as being anything having a pH of higher than 7.
Substances that are at a pH of 7 are considered neutral, like water (H2O)
The pressure is directly proportional to temperature (when the pressure decrease the temperature decrease too). Because the air parcel expands so the molecules will not interact with each other as much.
The energy of the particles does not change but the fact that the particles are more spaced out means the parcel is cooler.
so now, the warmer a parcel of air the more water vapor it can hold. so, if a parcel of air cools it's ability to hold water vapor drops and if it drops to a low enough point that is when the water vapor will condense and turn back into liquid water. This is how clouds and precipitation form on the the windward side of the mountain.
Answer:Answer:5.95 LExplanation:V1/V2 = T1/T24.82 L/V2 = 243.1K/300.1KV2 = 4.82*300.1/243.1 L = 5.95 L
Explanation: The volume of the balloon is 400 m3. To what temperature must the air in the balloon be heated before the balloon will lift off. (Air density at 10 oC is 1.25 kg/m3.)
Answer:
0.0222 mol KCl
Explanation:
2 KClO3 (s) 2 KCl (s) + 3 O2 (g)
2.73 g x mol
x g KCl = 2.73 g KClO3 x[ (1 mol KClO3)/ (122.5 g KClO3) ] x [(2 mol KCl)/ (2 mol KClO3)]
x g KCl = 0.0222 mol KCl
