How much heat must be absorbed by 50 grams?
Joule (J) is a unit of energy.Gram (g) is a unit for mass.
What is the amount that must be absorbed to start a reaction?
That is referred to as the activation energy.
Is the total mechanical energy of bumper cars conserved?
If you keep your foot on the floor you are adding energy all the time, but if two cars meet without drive engaged, the total energy before and after must balance. Of course kinetic energy can be absorbed by the car's bodywork so the resultant kinetic energy will be altered by collisions. Some energy will also be absorbed by the floor and appear as heat due to friction.
What foods are highest in energy?
I think butter at 750 calories per 100 grams must be the top or very near it.
What has to happen for a disaccharide to be absorbed?
Hydrolysis must occur before a disaccharide can be absorbed into the bloodstream. A water molecule is added during this process.
How much heat must be absorbed by 50 grams?
Joule (J) is a unit of energy.Gram (g) is a unit for mass.
How much heat energy must be absorbed to completely melt 35 grams of h2o at o degrees?
it will be 11,700J since the formula would be: q=mHf=35g x 334 J/g= 11,700 J
How much heat energy must be absorbed to completely melt 35.0 grams of water at 0 degrees Celsius?
Ice at 0 deg C has a latent heat of melting of 335 kJ/kg. If you have 35 grams (0.035 kg), then it would take exactly 11.725 kJ to melt the ice to get 35 grams of water at 0 deg C.
What is the amount that must be absorbed to start a reaction?
That is referred to as the activation energy.
The heat of fusion for water is the amount of energy that must be absorbed for water to what?
Melt.
When an electron gets excited is energy released or absorbed?
To get excited, it must absorb energy. To get back to its ground state, it releases energy.
How much energy in joules must be absorbed to convert to Na all the atoms present in 1mg of gaseous Na when the first ionization energy is 495.8 kj per mol?
21.6 J
What happens to electrons when pigments in photo-systems 2 absorb light?
Light or photons are little packets of energy. When this energy is absorbed by an electron it boots the electrons energy and the electron jumps to a higher orbital shell position (which must be vacant of its electron). The electron can only do this when the energy needed for the jump and the energy in the incoming photon match. Thus specific colours of light are absorbed depending on the element present.
What must be absorbed for a solid to melt?
They must gather close together until they can't bunch anymore and then they start to melt because they ran out of space.
How must microwaves interact with matter if they cause food and most containers to heat up in a microwave oven?
The waves of energy must be absorbed by the food so that the energy the wave was carrying is transferred as heat.
Name one quantity that must be know in order to determine the amount of heat associated with a body?
There are three: Energy absorbed by a body is directly proportional to the rise in temperature of a body Heat energy absorbed by a body is directly proportional to the mass of the body Heat energy absorbed by a body depends upon its nature and is commonly called specific heat capacity.
Why must food be absorbed?
Food must be absorbed so the body can get all the nutrients from the food.
