3rd option please and good luck hope you pass...........
Answer:
physical properties of gases, that is, pressure, volume, temperature, and amount of gas
Answer:
A
Explanation:
Since acceleration is the change of velocity and f=ma, the change in velocity is dependent on force and mass. Since the force on all of the objects is the same, the one with the least mass will accelerate the most. Object A is the least massive at a mass of 0.5kg, meaning that its velocity will change the most. Hope this helps!
Calculate the heat gained by the water first.
q = mCpΔT
m = 20.0 g
Cp = 4.186 J/g°C
ΔT = T(final) - T(initial) = 15.0°C - 10.0°C = 5.0°C
q = (20.0)(4.186)(5.0) = 419 J
This is equal to the heat lost by the metal, so calculate Cp for the metal, given:
q = -419 J (negative because heat was lost)
m = 5.00 g
ΔT = 15.0°C - 100.0°C = -85.0°C (negative because the temperature decreased)
q = mCpΔT —> Solve for Cp —> Cp = q/mΔT
Cp = -419 / (5.00 • -85.0) = 0.986 J/g°C
Iron doesn’t belong on this list
