What happens to the movement of molecule when their temperature is raised?
They begin to move faster. The increased temperature increases the energy of the molecule.
What happens to the enzyme rennin when the temperature is raised to the boiling point?
Disrupted.
What effect does adding a solute have on the boiling of solution?
The solution freezes at a lower temperature and boils at a higher temperature.
Why the reaction between magnesium and acid goes faster when the temperature is raised?
The atoms have greater kinetic energy and move faster when the temperature is raised, resulting in more frequent contact between the magnesium atoms and acid molecules, which will cause the rate of the reaction to increase.
Is the vapor pressure of a liquid a linear function of temperature?
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
What happens to the solubility of salts when temperature is lowered or raised?
In general, the solubility of a salt increases as the temperature is raised, and thus decreases when the temperature is lowered.
What does elevated temp mean?
raised temperature or raised temperarely
How much heat is required to evaporate a gram of liquid water at room termperature?
First, the water must be raised to a temperature of 100 degrees - this requires 4.181 joule/(degree x gram). For example, if your "room temperature" is 20 degrees, multiply that by 8. Then you have to actually evaporate it - that costs 2260 joules/gram.
What cellular event is being altered in cardiac tissue when temperature is raised or lowered?
When the temperature is raised, ensymic actibvity and metabolism increases. The opposite occurs when temperature is lowered.
Can you have more than one exponent on top of a number?
Yes, you can, but it starts getting complicated. You can, for example have a number raised to an exponent that is itself a number raised to an exponent, or you can have a number raised to an exponent and the result raised to another exponent.
When the temperature of body is raised by 100c the rise in temperature of the body in kelvin is?
273 k
What is the potiential energy of the 85 kg rock?
For every meter it's raised, it gains 833 more joules of gravitational potential energy.
How much energy does it take to heat water from 33degrees F to 34degrees F?
The specific heat capacity of water is about 4180 joules per (kg * kelvin), so you need the mass of the water, and the temperature rise in kelvin (or degrees celcius) example: 1 kg water raised 33 to 34 deg. F ( 0.555 deg. celcius) so, 1 * 0.555 = 0.555, then 0.555 * 4180 = 2320 joules
How many calories would it take to raise the temperature of 200 grams of water from 5 degress celsius to 85 degrees celsius?
m=225 g Delta T (change in temperature)= 33 C degrees c (specific heat water liquid)= 1 cal/g(C) Q=? Q=mc(delta T) Q=225g(1 cal/g(C degrees))(33 C degrees) Q= 7425 calories
When a number is raised to zero does it have the same value as another number is raised to a zero?
Yes because any number raised to the power of zero is always equal to 1
What is a number raised to the second power?
A number raised to the second power is a number times itself. This can also be stated as a number squared.
When the temperature of a solid is raised?
They usually expand and when the temperature gets high enough, turns to liquid.
