Answer:
3.91x10²³ atoms of lead
Explanation:
In chemistry, a mole of a substance is defined as 6.022x10²³ particles that could be atoms, molecules, ions, etc.
As you can see, in the problem, you have 0.650moles of lead in a fishing line sinker, the present atoms are:
=<em> 3.91x10²³ atoms of lead</em>
Answer: Object B will heat up more.
Explanation:
The formula for specific heat is as follows.
Q =
Where,
Q = heat provided
m = mass
C = specific heat
= change in temperature
Now, both the objects have same mass and equal amount of heat is applied.
According to the formula, the equation will be as follows.
=
=
Cancel m from both sides, as mass is same. Therefore,
=
Cancel out the initial temperature and put the values of specific heat, then the equation will be as follows.
=
Therefore, from the above equation it can be concluded that the object with low specific heat will heat up more as its specific heat will be inversely proportional to its final temperature.
Hence, object B will heat up more.
