Answer: V= 44. 6 L

Explanation: use Boyle's Law

P1V1 = P2V2

Derive to find V2:

V2 = P1V1 / P2

= 937.57 Pa( 12.5 L ) / 262.52 Pa

= 44.6 L

A 68-g sample of sodium is at an initial temperature of 42 °c. if 1840. joules of heat are applied to the sample, what is the fi
nadezda [96]

Answer:

Final T = 64.0°C.

Explanation:

  • The amount of heat absorbed by Na (Q) can be calculated from the relation:

<em>Q = m.c.ΔT.</em>

where, Q is the amount of heat absorbed by Na (Q = 1840 J),

m is the mass of Na (m = 68.0 g),

c is the specific heat capacity of Na (c = 1.23 J/g °C),

ΔT is the temperature difference (final T - initial T) (ΔT = final T - 42.0°C).

∵ Q = m.c.ΔT.

∴ (1840 J) = (68.0 g)(1.23 J/g °C)(final T - 42.0°C)

(final T - 42.0°C) = (1840 J)/(68.0 g)(1.23 J/g °C) = 22.0°C.

<em>∴ final T</em> = 22.0°C + 42.0°C = <em>64.0°C.</em>
