Answer:
Heat capacity units: J/K
Explanation:
Heat capacity (C) is the amount of heat (Q) required to raise the temperature(T) of a substance by a unit degree.
It is usually expressed in terms of J/K
Heat capacity is an intensive property i.e. it is not dependent on the amount of the substance. i.e, the amount of heat required to raise the temperature of 1 g of copper per kelvin would be the same as that corresponding to 100 g.
The density in kg/m³ = 1.14 x 10⁴
<h3>Further explanation </h3>Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density , g/cm³ or kg/m³
m = mass , g or kg
v = volume , cm³ or m³
A density of Lead : ρ = 11.4 g/cm³
the density in kg/m³ :
Answer:
Final temperature of the gas = -146.63 °C
Explanation:
At constant pressure, volume and temperature of the gases are related as:
Where,
V1 = Initial volume = 1.00 L
V2 = Final volume = 2.40 L
T1 = Initial temperature = 30.5 °C = 30.5 + 273.15 = 303.65 K
Now, substitute the values in the above equation,
T2 = 126.52 K
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
T( °C) = T(K) - 273.15
= 126.52 - 273.15 = -146.63 °C
