Answer:
Mass is Universal and weight is tied to the strength of the gravitational force of the planet .
Explanation:
The reason is because without mass you have no weight witch means if you have a certain amount of mass you will have a certain weight .
Answer of question 1 is When the buoyant force is greater than the force of gravity
answer of question 2 is true
answer of question 3 is the object is more dense than the fluid
answer of question 4 is you can't because steel will always sink since it is more dense than water
answer of question 5 is it has a low density
The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.
Answer:
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
Explanation:
The formula for for the heat (q) absorbed by an object is
q = mCΔT, where
m = the mass of the sample
C = the specific heat capacity of the sample. and
ΔT = the change in temperature
1. What you must do
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
2. Sample calculation
For this example, I assume that the specific heat capacity of AlF₃ is 1.16 J·K⁻¹mol⁻¹
.
(a) Calculate ΔT
(b) Calculate m
