A piece of hot metal is put into an equal mass of water. The water temperature rises 5o and the metal’s temperature drops 10o. W
Mice21 [21]

Answer:

The answer to your question is     Cm = 2.093 J/kg°C

Explanation:

Data

mass metal = mass of water

Δ water = 5°

Δ metal = 10°

Cm = ?

Cw = 4.186 J/Kg°C

Formula

              for metal       for water

               mCmΔTm  = mCwΔTw

Cancel mass of metal

                  Cm ΔTm  =  CwΔTw

solve for Cm

                         Cm = (CwΔTw) / ΔTm

Substitution

                         Cm = (4.186 x 5) / 10

Simplification

                         Cm = 20.93 / 10

Result

                         Cm = 2.093 J/kg°C

Solve this problem using the appropriate law. (Remember that ) What is the pressure of 1.9 mols of nitrogen gas in a 9.45 L tank
dedylja [7]
PV=nRT

You are funding pressure and you have V = 9.45L, n = 1.9 moles, R = gas constant, and T = 228 K

P(9.45L) = (1.9moles)(0.0821)(228K)

Find P

Multiply

9.45P = 35.57

Divide

P = 3.76 L of N

Answer should be 3.76 liters of nitrogen
