Because the mass is how much of something is in an object, gold and silver can have the same mass but have very different weights.
Hope I helped!
3) Volume is the amount of space an object takes up.
6) Gallons and inches are customary units of measurement, while (grams, kilograms, meters, centimeter, milliliter) are metric units of measurements.
8) When using a thermometer, the liquid goes up in the tube when the temperature increases. The liquid goes down in the tube when the temperature decreases.
9) The instrument used to find the volume of a liquid is a graduated cylinder.
15) Units of measurement that can be used to measure mass are called grams and kilograms.
17) The temperature is measured in Fahrenheit in the customer system and Celsius in the metric system.
Answer:
P (H₂) = 741 torr
Explanation:
Let's begin by listing out the given parameters:
Temperature (water) = 298 K, volume = 45.6 mL,
atmospheric pressure, P (total) = 765 torr, vapor pressure of water, P (H₂O) = 24 torr
To get the pressure of inside the tube, P (H₂), we apply Dalton's Law of Partial Pressure and we have:
P (total) = P (H₂) + P (H₂O)
P (total) = 765 torr, P (H₂O) = 24 torr
P (H₂) = P (total) - P (H₂O) = 765 - 24
P (H₂) = 741 torr
It therefore becomes clear that the pressure of H₂(g) is 741 torr
A.) The number of electron shells increases.
Protons and neutrons are made up of tiny particles called quarks.
A proton is a baryon made up two Up and one Down quark.
A neutron is made of two Down quarks and one Up quark.
The Up quarks possess a 2/3 positive charge while the Down quark possess a 1/3 negative charge.
When we refer that a proton consists of two Up quarks and a Down, this simply means that its net appearance matches this description.
It is thought that quarks themselves are surrounded by gluons.
Gluons are the basic particles underlying the strong interaction between protons and neutrons in the nucleus.
