Answer:
6.217 pounds
Explanation:
We are given;
- Density of body fats 0.94 g/mL
- Volume of fats removed = 3.0 L
We are required to determine the mass of fats removed in pounds.
We need to know that;
Density = Mass ÷ volume
1 L = 1000 mL, thus, volume is 3000 mL
Rearranging the formula;
Mass = Density × Volume
= 0.94 g/mL × 3000 mL
= 2,820 g
but, 1 pound = 453.592 g
Therefore;
Mass = 2,820 g ÷ 453.592 g per pound
= 6.217 pounds
Thus, the amount of fats removed is 6.217 pounds
Answer:
An alcohol thermometer can measure the freezing point of a liquid that freezes at −80 °C.
Explanation:
A thermometer is a device used to measure temperature. A thermometer must contain a thermometric substance. A thermometric substance is any substance having a particular physical property that changes with temperature.
For all liquid-in-glass thermometers, the property that changes with change in temperature is the height of the liquid. There are two kinds of liquid-in-glass thermometers; mercury-in-glass thermometer and alcohol-in-glass thermometer.
Alcohol-in-glass thermometer measures very low temperatures up to as low as -115°C. If it measures such a low temperature, then it can efficiently measure -80°C hence the answer.
Alcohol-in-glass thermometers have a narrower temperature range than mercury-in-glass thermometer. The later is well adapter for the measurement bof higher tempetures up to 357°C.
Yeah of-course!! It's valency by group most of the chemical property like electronegativity, ionization energy etc. by the combination of groups and periods...
Answer:
Geothermal power comes from Earth's internal heat
Explanation:
The description applied to power sources tends to match the names applied to the source of energy. Sometimes Latin, or other word derivations are used.
For example, "hydro-" refers to water, so it is no surprise that hydroelectric power comes from the movement of water. Of course, "nuclear" refers to the nuclei of the atoms that are split to release energy in a nuclear power plant. Similarly, "geo-" refers to Earth, and "thermal" refers to heat, so "geothermal" energy is the name given to energy derived from Earth's heat.
