The answer is unrestrained hair.
Have a nice day!
germanium has 32 protons in its nucleus
Answer:
1610.7 g is the weigh for 4.64×10²⁴ atoms of Bi
Explanation:
Let's do the required conversions:
1 mol of atoms has 6.02×10²³ atoms
Bi → 1 mol of bismuth weighs 208.98 grams
Let's do the rules of three:
6.02×10²³ atoms are the amount of 1 mol of Bi
4.64×10²⁴ atoms are contained in (4.64×10²⁴ . 1) /6.02×10²³ = 7.71 moles
1 mol of Bi weighs 208.98 g
7.71 moles of Bi must weigh (7.71 . 208.98 ) /1 = 1610.7 g
The data provided is of specific heat
The relation between specific heat, heat absrobed and temperature change is
Q = mass of substance X change in temperature X specific heat
Now if we have provided same amount of heat to two substances of different specific heat, the substance with lower specific heat will heat up more as compared to the substance with higher specific heat.
[Specific heat is the amount of heat absorbed by a substance (say nickel) to raise it temperature by one degree if we have taken one gram of substance]
Higher the specific heat higher the heat required to raise the temperature upto same extent.
Thus as the specific heat of Nickel is less, it will heat up easily
Answer: Granite, because it needs to absorb more energy to increase its temperature
