Gravity. I guess it depends on what you mean by mass and weight. I think you mean like the weight of something on the moon so i will just explain that. The Moon has less weight so that means less gravity pulling down. The less gravity the lighter you are. a 200 pound man would be 33 pounds.

*put your weight in this and it ill tell you your weight on other world not just the moon. If you scroll down, you will notice it even tell you your weight on a neutron star. Ouch....:)

Why is there a change of mass after combustion?
When something burns, it is getting oxidized. Combustion reactions involve oxygen. During oxidation, 1.the substance forms a bond with oxygen (or) 2.an element of the substance breaks away from it to bond with oxygen. The mass of the reactants (substance + oxygen) are always equal to the mass of the products. If the mass referred to in the question is the mass of the substance, then you can say that the mass has increased due to the addition of oxygen when the substance is forming a bond with it. However in reactions where an element breaks off the substance to bond with oxygen, the mass in question can be assumed to be that of the major portion of the substance. Then, it may be said that the mass of the substance has reduced. For example, carbon in a substance combines with oxygen to form CO2. Thus the substance loses carbon and its mass reduces.
After a fire the ashes have less mass and take up less space than the trees and vegetation before the fireHow can this be explained in terms of the law of conservation of mass?
No, it is not an exception . The supposed loss of weight is accounted for by the gases escaping from the reaction . If we weight the gases and the ashes , it will be the same as the log of wood There are no exceptions to the law of conservation of mass
How much does a hot-air balloon weigh?
The weight of a hot-air balloon can vary depending on its size and design. On average, a small hot-air balloon can weigh around 250-400 pounds (113-181 kilograms), while larger ones can weigh over 1,000 pounds (453 kilograms) or more.
What does proverbial cloud mean?
Well, how much wood could a wood chuck chuck if a wood chuck could chuck wood? Im joking. It means to be in a solitary position.
Why do the same objects fall at the same rate?
For example take a bowling ball and a bouncy ball... Sure the bowling ball has more mass so the pull of gravity is greater on that object but this also means the surface area of the bowling ball causes air resistance thus slowing it back down. The bouncy ball on the other hand has less mass and is thus effected less by gravity but its surface area is much less so it "pierces" through the air because it has very little air resistance. Hope that helps :) Another opinion: In a vacuum all objects fall at the same rate. The only thing that causes objects to fall at different rates on Earth is their aerodynamic shape. To demonstrate this the astronauts on an Apollo moon mission (Apollo 15 maybe) dropped a feather and a hammer. They landed at the same time, because there is virtually no atmosphere on the moon. On Earth the feather would tend to "float" down, riding on air.
How are the wood block golfball and water alike?

Does an objects weight change in the water?
No. Weight = mass * g, where g = 9.8 m/s2, a constant. The mass of an object does not change unless it undergoes a chemical or nuclear change. Hence its weight is a constant too. However, the "apparent weight" changes because the inherent weight is now compensated somewhat by buoyancy, acting in the opposite direction as gravity. The weight of a piece of wood in water will be completely opposed by the buoyancy and so it floats. The weight of a concrete block cannot be completely compensated by buoyancy and so it sinks. ========================
What is theweight of a block of wood iin pounds?
A block of wood can be of different sizes; this will affect the mass, and weight, a lot. To a lesser degree, the weight of a block of wood will also depend on the density, since different types of wood have different densities.
Why is making wood to furniture is physical change?
There is nothing to change no color change so it is a physical change
When wood is burned in a closed container its mass does not change is that observation or law?
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
Weight and mass relationship?
An object's mass is the quantity of matter that comprises it ... the total protons, neutrons, electrons, lint, moisture, dirt, wood-chips, and anything else of which the object is composed. It belongs to the object, and doesn't depend on where the object is or in what position it is, etc. An object's weight is the gravitational force between the object and any other mass. That force depends on both the object's mass and the other mass, and also on how far apart they are. An object's weight is its mass multiplied by the acceleration due to gravity in the place where the object is located at the moment ... so it can change. For example, your weight would be FW=(your mass in kg)*(9.80m/s2) because 9.80m/s2 is the acceleration due to gravity on Earth.
Describe how a physical property such as mass or texture can change without causing a change without causing a change in the substance?
Lets say you had wood. You can grind around the surface of the wood to make its texture softer or use a saw to cut the wood so each separate piece has a smaller mass. However, after these changes, you still have the same substance as before (in this case, wood) ^_^

How is the mass of a wood block related to its volume?
Density of wood = mass/volume
