Document Summary
95c+ 32 where c is celsius (f-32) x59where f is fahrenheit. Anything that takes up space and has a mass. Mass is referred to the amount of matter in the object. Measure the force it takes to accelerate an object. Weight is the force gravity exerts on an object. The force is directly proportional to the mass. The weight change as the force of gravity change. Law of conservation of matter: matter never created nor destroyed when converted. Physical property: characteristic of matter that does not influence its chemical composition. Density, color, hardness, phase change, and electrical conductivity. Physical change: change in the state or property of matter without a change in its chemical composition. Cutting paper, dissolving sugar, grinding solid into power. P. s. even though we cut the paper, it is still paper. Instead of being a whole paper, it is now in pieces.
