How does the volatility of a hydrocarbon change as its carbon chain length increases?
it decreases as the molecules get higher
How does a temperature increase cause the rate of a reaction to increase increase?
It increases the kinetic energy of the molecules (APEX)
Why does the solubility of a gas generally decrease with an increase in temperature?
As the temperature of the water increases, its vapour pressure increases, meaning there is more water molecules leaving the surface than before. Gases have weak intermolecular forces and therefore high vapour pressures and will therefore be readily evaporating already. The increased presence of water vapour above the water (i.e. increased humidity) reduces the amount of the gas able to condense back into the liquid, meaning less gas is dissolved.
Why does solubility of alum in water change with temperature?
The water molecules spread out as temperature increases, which allows the alum to dissolve more readily. Conversely, as temperature decreases, the water molecules become more compact which causes the alum to be less soluble.
Why does the solubility of water decreases as temperature increases?
because increase in molecular werght increases the hydrophobic part and decreasesv the hydrophilic part which is soluble. therefore increase in insuluble part decreases the solubility.
How does the volatility of a hydrocarbon change as its carbon chain length increases?
it decreases as the molecules get higher
Does the volume of a gas always increase when temperature increases and pressure decreases?
Yes. When the temperature increases the molecules are more excited and move farther apart. When the pressure decreases, the molecules also have more space and will fill the void.
Why air pressure decreases with an increases in altitude.?
there is less oxygen and the molecules are more spread out
When density increases the number of molecules in a volume increases decreases varies or stays the same?
For the same gas, more density means more molecules per unit volume.
How does the gas volume vary with change in pressure?
This one is explained in Boyle's Law. It was stated that if the temperature is constant, the pressure is inversely proportional to the volume. Thus, if the pressure increases, the volume decreases. It is also the same as if the pressure decreases, the volume of the gas increases.
What happens to the air molecules in a divers lungs as the pressure increases during a dive?
As the diver descends deeper into the water, the pressure increases. This causes the air molecules in the diver's lungs to compress, leading to a decrease in volume. In order to maintain equilibrium with the increasing pressure, the air molecules in the lungs will be forced into smaller spaces, potentially causing discomfort or injury if not managed properly through controlled breathing techniques.
When air is heated it rises this is because?
The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.
Is pressure higher or slower when molecules move faster or slower?
Molecules move more rapidly when heated as their kinetic energy is increased so their speed increases.
How and why matter changes state?
the factors that effect the state of matter are:-temperaturepressurethe matter change their state because of the above. if the temperature increases the kinetic energy or the energy to move of the molecules and it tends to move away from each other that results in change of state. if the temperature decreases the kinetic energy decreases which pulls the molecules together and again results in the change of state.as the pressure increases the intermolecular space decreases and thereby changes the state like in the LPG (Liquefied Petroleum Gas) where petrol is pressurized to become liquid.thus we can conclude that the change of state of matter takes place to satisfy the surroundings of the matter.
Why does viscosity vary with respect to temperature?
the increase in temperature increases the K.E of the molecules and distances among molecules therefore the force of friction decreases as the result of which molecules move faster and viscosity becomes decreased....
When the concentration of molecules on both sides of a membrane is the same (equilibrium) the molecules will?
reach dynamic equilibrium. Answer : move across the membrane in both directions (equilibrium).
As a parcel of air increases in altitude its pressure will?
No, the density lowers. When air expands, the volume of area it takes up increases while the density decreases. The molecules move apart.
