The question is incomplete, the complete question is;
An alcohol thermometer makes use of alcohol's changing _______ in order to measure temperature. As the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
A.
mass
B.
state
C.
chemical composition
D.
density
Answer:
D.
density
Explanation:
Every kind of thermometer makes use of a change in a particular physical property of a substance as a measure of temperature. It must be a property that changes with temperature.
Density of a substance changes with temperature. Even though the mass of alcohol in glass remains constant, but its volume increases or decreases with change in temperature leading to a change in volume and consequently a change in density of the alcohol in glass. This change is used as a measure of the change in temperature.
Answer:
It would take 64 1-cm cubes to construct a 4-cm cube.
Explanation:
The volume of a cube is equal to the edge raised to the power of 3.
A 1-cm edge cube has a volume of V₁ = (1 cm)³= 1 cm³
A 4-cm edge cube has a volume of V₄ = (4 cm)³= 64 cm³
The number of small cubes required to fill the same volume than the big cube is:
Since there are no conversions to be done just add them as is
a) 1 g
b) 1.0 kg
c) 22 L
d) 3.6 cm
<span>e) 104.9 g</span>
Answer:
Adding one proton to an atom of lithium with 3 protons, 4 neutrons and 3 electrons would form a _beryllium ion_. The new atom have 4 protons and 4 neutrons since Be has a mass number of 9 then it has to form an ion. Hope this helps! PLEASE GIVE ME BRAINLIEST!!!! =)
There are four quantum numbers: the n, l, m and ms. When the orbital is 2p, it means that n=2 and l = 1. The n number takes the whole number before the sub-orbitals. Then, the designation for the p orbital is l=1. Now, the possible values if m is a range from -l to l. H<em>ence, in this case, that would be: -1, 0, 1.</em>
