4.20 As shown in Example 4.6, the fugacity of a van der Waals gas is given by a fairly simple expression if only the second virial coefficient is used. To this degree of approximation, derive the expressions G,...
The constant volume Molar heat capacity of ethane, C2H6(g) is 44.3 J/mol-K. When 9.0 kJ of heat is removed at constant volume from 90 grams of ethane, the final temperature is 53oC. What was the approximate initial temperature of the C2H6 before the heat is removed. The correct answer is +120oC. Please show work and explain
6。C. designates the heat capacity measured at constant volume. We could imagine measuring the heat capacity of some material at two different fixed volumes. We wouldn't necessarily get the same answer and thus C, can itself be a fiunction of volume. It tuns out that if we know C at one volume we don't need to measure it at another volume if we know the equation of state Show that: ac You will need to make use of the definition...
What is the heat capacity at constant volume, Cv, of an ideal gas, in ??? ?? °? if the constant pressure heat capacity, Cp = 0.124 ?? ??? ? and the molar mass of the material is 28 ton/ton-mole?
1. Define enthalpy and entropy in terms of heat capacity (at constant pressure). Explain what the math accomplish. 2. What is an Arrhenius plot and what does one determine using it? Show a simple version. 3. What is calorimetry and how is "heat" related to deltaH?
3,1 moles of an ideal gas with a molar heat capacity at constant volume of 5,1 cal/(mol∙K) and a molar heat capacity at constant pressure of 7,7 cal/(mol∙K) starts at 317,6 K and is heated at constant pressure to 335,9 K, then cooled at constant volume to its original temperature. How much heat (cal) flows into the gas during this two-step process? Answer in two decimal places.
An ideal monatomic gas has a molar heat capacity Cmp at constant pressure. What is the molar heat capacity at constant volume of an ideal diatomic gas?
The value of the heat capacity for a substance depends on
whether it’s measured under constant pressure conditions or
constant volume conditions. The constant-pressure molar heat
capacity is given by
= (dq/dT)P
and the constant-volume heat capacity is given by
= (dq/dT)V
Note that we use d instead of
because q is not a state function of temperature, volume, and
pressure; its value depends on how we execute the process.
Here are several questions regarding heat capacity.
a. When we...
