Answer:
7.01 g
Explanation:
Answer:- Mass of the titanium alloy is 7.01 g, choice C is correct.
Solution:- The heat of fusion is given as 422.5 joules per gram and it also says that 2960 joules of heat is required to melt the metal completely.
The suggested equation is, Q=mHf
where Q is the heat energy, m is the mass and Hf is the heat of fusion.
Since, we are asked to calculate the mass, the equation could be written as:
m=q/H5
Let's plug in the values in it:
m= 2960J/ 422.5j/g
m = 7.01 g
So, the mass of the titanium alloy is 7.01 g, choice C is correct.
Answer:
Einstein proposed that electromagnetic radiation has a wave-particle nature, that the energy of a quantum, or photon, depends on the frequency of the radiation, and that the energy of the photon is given by the formula Ephoton=hv.
