All of the planets orbit around the sun, due to the gravitational pull of the sun
Answer:
T₂ = 182 K
Explanation:
Given that,
Initial pressure, P₁ = 120 kPa
Initial temperature, T₁ = 0˚C = 273 K
We need to find the final temperature when the pressure is 80 kPa.
We know that, Gay Lussac's Formula is :
So, the new temperature is equal to 182 K.
Answer: 2.04L
Explanation:
coldest temperature = -10°C
mass of solvent = 6.50kg
freezing point depression = kb*m
Where kb = molar freezing point depression constant, 1.86
10 = 1.86 * molality of ethylene glycol
10 = 1.86 * moles of ethylene glycol/mass of solvent
10 = 1.86 * moles of ethylene glycol/6.5
10*6.5 = 1.86 * moles of ethylene glycol
Moles of ethylene glycol = 65/1.86
Moles of ethylene glycol = 36.11
36.11 mol * 62.1 g/mol = 2242.43g = 2.24kg
1 L = 1000 mL x 1.11 g/mL = 1100 g = 1.1 kg
2.24 kg / 1.10 kg/L = 2.04 L
Answer:
The bonds between water molecules are easily broken by the strong ions of ionic compounds
Answer:
"Kinetic energy of the gas is more as compared to that of the liquids. But when compare it to the solid, kinetic energy of liquid is more."
Explanation:
a) Relatively high density : This happens as a result of the tight or packed or can be say close arrangement of the particles.
b) Ability to diffuse : As we know that in gases the constant and the random motion of the particles of the liquid leads to diffusion. But it is very slow as compared to the gases and also porque liquid particles are close together.
c) Ability to evaporate:This happens as a result of the molecules of the liquid having different kinetic energies with particles having higher than that of the average energies that move faster.
