La temperatura del gas contenido en el recipiente es de -259,35 ° C
Explicación:
Para encontrar la unidad de grados en Celsius (° C) en este caso, se usa la ecuación de la ley de los gases ideales.
PV = nRT
Donde P es la presión, V es el volumen, T es la temperatura, n es el número de moles y R es la constante universal de los gases.
P = 143 kPa = 1,4113 atmósferas
V = 2,00 L
n = 2,49 mol
R = 0.08205746 atm * L / mol * K
Resolver para T sería: PV / nR
T = (1.4113 atm * 2.00 L) / (2.49 mol * 0.08205746 atm * L / mol * K)
T = 2,8226 / 0,2043
T = 13,8 K = -259,35 ° C

A sample of water is heated from 60.0 °C to 75.0°C by the addition of 140 j of
kupik [55]

Mass of the water : 2.23 g

<h3>Furter explanation</h3>

Heat

Q = m.c.Δt

m= mass, g

c = heat capacity, for water : 4.18 J/g° C.

ΔT = temperature

Q= 140 J

Δt = 75 - 60 = 15

mass of the water :

\tt m=\dfrac{Q}{c.\Delta T}=\dfrac{140}{4.18\times 15}=2.23~g
