You have three mugs of tea:
a. Is a small mug. It is 100°F
b. Is a large mug. It is 120°F
c. Is a small mug. It is 120°F
Put these mugs in order. Start with the mug with the SMALLEST amount of thermal energy first and end with the mug with the LARGEST amount of thermal energy.
__2__ C. is a small mug. It is 120°F
__3__ A. is a small mug. It is 100°F
__1__ B. is a large mug. It is 120°F
Answers
Answer:
ACB
Explanation:
Thermal energy is the average sum of all kinetic energy of all the molecules of gases. The correct order of mug in decreasing thermal energy is C>A>B.
What is Thermal energy?
Thermal energy is a energy which is possess by a moving object. It is directly proportional to kinetic energy of the molecules. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy. Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases.
Mathematically,
K.E=2/3KT
Where,
K= Boltzmann constant
T is the temperature
Between A and C whose volume is same, 120°F is the highest temperature so, C will have high thermal energy than A. C will have lowest thermal energy as it has volume larger than that of A and C.
Therefore, the correct order of mug in decreasing thermal energy is C>A>B.

which of the following is NOT a characteristic of minerals
A. Occur in gaseous and liquid state
B. Formed by inorganic processes
C. naturally occurring
D. definite chemical composition
Answers
Answer:
A. Occur in gaseous and liquid state
Explanation:
The choice that is not a characteristic of minerals is that minerals occur in gaseous and liquid state.
All minerals are solid inorganic compounds.
A mineral is an inorganic compound that is formed naturally. They have a definite and specific chemical composition. Minerals are the building blocks of rocks. When minerals aggregates together, they form different rock types. There is no known mineral that is in fluid state. All minerals are solids. Examples are quartz, kaolinite, gypsum e.t.cWhat is the mass of protons neutrons and electrons PLZ HURRY

2.54 mL of ethanol to mol ethanol (Hint: the density of ethanol is 0.789
g/mL.)
Answers
0.04350179862
Explanation:
Make sure to check for sig figs though. Basically, you have 2.54 mL and you multiply that by the 0.789 g/mL and mL cancels out and you are left with 2.00406g. There are 46.06844 grams per mol of ethanol, so to cancel out grams we multiply by 1/46.06844. And then we are left with 0.04350179862 mol

1. An oxide of chromium is found to have the following % composition: 68.4% Cr
and 31.6% 0. Determine this compound's empirical formula.
Answers
Answer:
Empirical formula is Cr₂O₃.
Explanation:
Given data:
Percentage of Cr = 68.4%
Percentage of O = 31.6%
Empirical formula = ?
Solution:
Number of gram atoms of Cr = 68.4 / 52 = 1.3 2
Number of gram atoms of O = 31.6 / 16 = 1.98
Atomic ratio:
Cr : O
1.32/1.32 : 1.98/1.32
1 : 1.5
Cr : O = 1 : 1.5
Cr : O = 2(1 : 1.5)
Empirical formula is Cr₂O₃.

If the number of equally likely sample outcomes of a single ASAP! stage of an experiment is 4, what is the total number of elements in the sample
space if the experiment has 3 stages?
OA. 16
OB. 12
OC. 64
OD. 81
Answers
Answer:
C. 64
Explanation:
Given:
The number of equally likely sample outcomes of a single stage = 4
Unknown:
Total number of elements if there are three stages= ?
Solution;
Probability is the likelihood of an event to occur.
In this problem;
For a single stage, the likely outcome is 4
So therefore;
For the 3 stages 4 x 4 x 4 = 64
Therefore, the total number of elements in the sample space of an experiment with 3 stages is 64

What is density?It is a ratio of substance's mass per unit of volume.Symbol most commonly used for density is р.The SI unit of density is kilogram per cubic meter .It explains how tightly a material is packed together.
There are 2 types of density :1)absolute density 2) relative density.Absolute density is the mass of any substance per unit volume and relative density is the ratio of density of a substance to the density of a given reference material.
Reference material used for relative density is water.The instrument used for measuring density or relative density of liquids is hydrometer. Density is measured at constant temperature and pressure.

Answers
Answer:
50. 54,915 J
51. 27.0 g
Explanation:
The dimensional analysis tells you how to compute these. Multiplying specific heat, J/(g·°C), by the product of mass and temperature change will give you energy.
__
50. (375 g)((70 -45) °C)(4.184 J/(g·°C)) = 54,915 J

Organic whole wheat flour sells in bags weighing 2.915 kilograms.
How much flour is this when rounded to the nearest tenth? Use a place value chart and number line to explain your thinking.
Answers
Answer:
2.920
Explanation:
This question tests your knowledge of approximation. If we look at the place values after the decimal point, we have, .915. This corresponds to hundredth, tenth and unit.
Since we have 9.15, in rounding it to the nearest tenth, we have to round it up to .920.
Hence, the weight of the flour to the nearest tenth is 2.920.
