The mass of titanium alloy is 7.01 g
<u><em>calculation</em></u>
Q=mHF
where
Q(heat)= 2960 j
M(mass) = ?
Hf( heat of fusion) = 422.5 j/g
make M the subject of the formula by diving both side of equation by Hf
M=Q/Hf
M= 2960 j/422.5 j/g = 7.01 g
The law is Newton's first law or called the law of inertia; Which just means that an object at rest stays at rest and an object in motion stays in motion and continues at the same speed and in the same direction unless acted upon by an outside force force.
Answer:
Physical properties
Explanation:
These properties are the ones that you can observe or collect by your senses, for example the color, the odor, the sound, the texture, etc. In this case the substance is not going to change to a new one, it could be that is changing of state.
The lightest is hydrogen and the heaviest is hassium.
