A calorimeter contains reactants and a substance to absorb the heat absorbed. The initial temperature (before the reaction) of the heat absorbent is measured and then the final temperature (after the reaction) is also measured. The absorbent's specific heat capacity and mass are also known. Given all of this data, the equation:
Q = mcΔT
To find the heat released.
Answer:
1.Physical. People measure water by themselves.
2.Physical. People chop wood.
Explanation:
(this is all I can answer for you. you have to explain it by yourself tho.)
I dont know if I'm correct so you should double check.
A mountain system is a geographic area containing numerous geologically realted mountains.
Answer:
C.Tritium
Explanation:
Isotopes are forms of an element with different mass number but same atomic number. Mass number is the sum of the number of protons and neutrons in the nucleus of an atom, while atomic number is the number of protons.
Mass number = protons +neutrons.
Atomic number = protons only
We can say that mass number = atomic number + number of neutrons.
The number of neutrons is what differentiates the isotopes of an element.
For hydrogen element, it has three isotopes namely; protium, deuterium and tritium which have 0,1 and 2 neutrons respectively. Thus the answer is C
