heat is treated as a reactant or a product
You can use Hess Law to determine the heat of the reaction and then if it is negative, it is exothermic (heat releasing). If it is positive, it is endothermic (heat absorbing).
Using a calorimeter.
If the light can not pass through a object it is opaque . The light will reflect or be absorbed by the object.
the heat released or absorbed in a reaction
It is converted into heat in the string and the environment.
If you are talking about a magnifying glass, the convex glass bends and concentrates the light waves and heat energy associated with those waves. Where the energy is concentrated becomes very hot. Flat or concave glass does not affect the waves. If you are talking about the inside of the car getting hot, that is because the light energy can pass through the glass and get absorbed by the material in the car, the darker the material, the more energy is absorbed. The energy absorbed from the light is them converted onto radiant heat which cannot pass through the glass and becomes trapped which allows the heat to build.
it depends on the units of the specific heat, but if they are J / goC then you would take your delta T (25-20) and multiply it by your mass (14g) and multiply by your specific heat. In this case it would be 5 * 14 * .11 = 7.7 (with whatever units of energy your specific heat is in.) Just make sure your units cancel out and you will get it right!
Too much heat would result in brake damage, which is absorbed in the brake drum.

q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.
23 percent of incoming solar energy is usually absorbed by the ozone. Temperature, not how much
2 kJ.
To the extent to which the energy is absorbed, yes. Reflectivity and color determine how much energy is absorbed, but no matter can reflect 100% of the energy striking it. Some will be absorbed by the molecules.
that's not a valid question
Joule (J) is a unit of energy.Gram (g) is a unit for mass.
If the light can not pass through a object it is opaque . The light will reflect or be absorbed by the object.
Approx. 15 kJ.
Heat gained by one object = Heat lost by the other. Does that help?
The answer is 1.24 kilojoules is absorbed in the reaction of 4.88g of barium hydroxide octahydrate with ammonium chloride. Kilojoule can be abbreviated as kJ.
