### Ideal Gas Properties and Specific Internal Energy CalculationIn this section, we will explore the properties of a specific ideal gas and determine the change in specific internal energy given varying temperature conditions. #### Given Properties and FormulaA particular ideal gas is characterized by the following equation for heat capacity at constant pressure \( C_{p0} \):\[ C_{p0} = A + \left( \frac{B}{T} \right) \]where:- \( A \) and \( B \) are constants.- \( T \) is the temperature in Kelvin (\( °K \)).- \( C_{p0} \) has units of \( \text{kJ} / °K \cdot \text{kg} \).The gas constant for this system is given by:\[ R = 0.25 \text{kJ} / °K \cdot \text{kg} \]The constants are:\[ A = 1.25 \]\[ B = 173.8029748 \]We are given two specific temperatures:- \( T_1 = 300°K \)- \( T_2 = 400°K \)#### ObjectiveDetermine the change in specific internal energy (\( u_2 - u_1 \)) in \( \text{kJ} / \text{kg} \). It is important to note that the assumption of constant specific heats is not valid for this calculation.#### Process1. **Integrate the specific heat capacity function to determine the change in internal energy:** Specific heat capacity at constant volume \( C_v \) can be related to \( C_{p0} \) as follows, considering the ideal gas relationship: \[ C_v = C_{p0} - R \]2. **Integrate \( C_v \) over the temperature range:** \[ u_2 - u_1 = \int_{T_1}^{T_2} C_v \, dT \] \[ \Rightarrow u_2 - u_1 = \int_{T_1}^{T_2} \left( A + \frac{B}{T} - R \right) \, dT \] Substitute the values of \(A\), \(B\), and \(R\): \[ u_2 - u_1 = \int_{T_1}^{

A certain ideal gas has the following properties: Cpo = A + (B/T) where A and B are constants and T is temperature in °K and Cpo has units kJ / K /kg. The gas constant is R = 0.25 kJ/ºK/kg and the constants A = 1.25, B = 173.8029748. For T₁ = 300 °K and T₂ = 400 °K, determine the change in specific internal energy, (u₂-u₁ ) in kJ/kg. You may NOT assume constant specific heats.

There are two experiments for this activity – make sure you include both. Experiment #1: Acceleration vs. Force In this lab you will determine the relationship between acceleration and net force. Choose a mass at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Applied Force. Graph Acceleration vs. Net Force. Graph this in Google sheets(you want a line graph - it should only have one line).

O You are running an industrial research study together with your project team to improve energy efficiency in a combustion process. The purpose of the research is to identify the optimum air-fuel ratio for the combustion process in a boiler under varying conditions of air supply and quality of fuel.

In order to fnd the specifc heat c of an unknown substance, you place 75 g of the substance in a 30 g copper calorimeter that contains 65 g of water, all initially at 20 °C. You then add 100 g of water at 80 °C, and measure the fnal temperature of the system to be 49 °C. Assuming no heat is lost to the environment, what is c? [Answer: c = 2200 J/kg. K] 즈
The gravitational constant g is 9.807 m/s² at sea level, but it decreases as you go up in elevation. A useful equation for this decrease In g is g= a - bz, where z is the elevation above sea level, a = 9.807 m/s², and b=3.32 x 10-61/s². An astronaut "weighs" 80.0 kg at sea level. [Technically this means that his/her mass is 80.0 kg.] Calculate this person's weight in N while floating around in the International Space Station (z=325 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel Immediately after the satellite stopped moving? The person's weight in N while floating around in the International Space Station Is The astronaut feels a gravitational acceleration of m/s² N.
