Answer:

23 atm

Explanation:

Step 1: Given data

  • Initial volume (V₁): 2.5 L
  • Initial pressure (P₁): 90 atm
  • Final volume (V₂): 10 L
  • Final pressure (P₂): ?

Step 2: Calculate the final pressure of the gas

If we assume constant temperature and ideal behavior, we can calculate the final pressure of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

P₂ = P₁ × V₁ / V₂

P₂ = 90 atm × 2.5 L / 10 L = 23 atm

As expected, since the volume increased, the pressure decreased.

iris [78.8K]

Answer: P= 1.64 atm

Explanation: solution attached.

Use Ideal gas law

PV= nRT

Derive for P

P= nRT/V R= 0.08205 L.atm/mol.K

Substitute the values.

A 100g sample of a metal was heated to 100oC and then quickly transferred to an insulated container holding 100g of water at 22o
Lady_Fox [76]

Answer:

B) The metal temperature changed more than the water temperature did, but the metal lost

the same amount of thermal energy as the water gained.

Explanation:

Heat capacity or thermal capacity is defined as the amount of heat required by a given mass of a material to raise its temperature by one unit which means that the heat capacity of the water, that is the quantity of heat required to cause a rise from 22°C to 35°C that is a rise of 13°C is the quantity of heat that caused the drop in temperature of the metal from 100°C to 35°C a change of 65°C

The water has more capacity to absorb heat or a higher heat capacity than the metal

However, the first law of thermodynamics states that energy is neither created nor destroyed, but it changes from one form to another. In this case, the thermal energy lost by the metal is the same as the thermal or heat energy gained by the water

Which of these would be a good topic for a descriptive investigation? A. how the Moon's appearance changes B. what kind of dog f
katen-ka-za [31]

A. how the Moon's appearance changes

Explanation:

Descriptive investigation use very careful observations and measurements to develop findings.

Most geologists, meteorologists and astronomers use descriptive investigation to develop their findings.

  • Since most of their subject matter is inaccessible.
  • Descriptive investigation is used for indirectly making inquiries
  • It involves the development of an inquiry without formulating any hypothesis.
