<h3><u>Answer</u>;</h3>
= 1.44 L
<h3><u>Explanation</u>;</h3>
Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at a constant temperature.
Mathematically;
<em>P α 1/V</em>
<em>PV =constant </em>
<em>Thus, P1V1 = P2V2 </em>
<em>P1 = 1.00 atm, V1 = 3.60 liters, V2 = ?, P2 = 2.50 atm</em>
<em>V2 = P1V1/P2</em>
<em> = (1× 3.6)/2.5 </em>
<em> = </em><u><em>1.44 L</em></u>

Hope this helps
Explanation:
Thermal energy, which is more commonly known as heat, is a form of energy. It is measured in joules. Thermal energy is an internal energy for a given system. Thermal energy is the cause for the temperature of a system.
Temperature is the measureable thermal property of a system. It is measured in Kelvin, Celsius, or Fahrenheit. The SI unit for temperature measurement is Kelvin.
Differences:
Thermal energy is not a directly measurable quantity whereas temperature is a measurable quantity.
• The temperature of an object can take negative values depending on the unit system used to measure the temperature, but the thermal energy of a system cannot be negative.
• Temperature is measured in Kelvin whereas thermal energy is measured in Joule.
• An object can lose or gain thermal energy in a state transition without changing the temperature of the system.

Did you see the part where I said that we did a nearly identical problem in class and to check the notes or the recording?
from the 19 protons
Answer:
+19
Explanation:
potassium, k, has 19 protons, 20 neutrons, and 19 electrons. what is the charge of the atom’s nucleus?
since only neutrons and protons are in the nucleus, the overall charge in the nucleus is +19 from the 19 protons
