The equivalent spring stiffness constant of a simple pendulum whose length of string is 6 ft and a suspended weight of 1.5 lb

(9 blanks) Derive the work done of an ideal gas undergoing isothermal expansion at temperature T1 if the volume changes from V1 to V2. Express in terms of P1 and P2. V2 W = V1 Where: p= TV By substitution: V2 dv W = vị V Applying the rules of integration, the word done will become W= In| Using: P1V1 = nRT & P2V2 = nRT The work done in terms of pressure is expressed as W = In >

THERMODYNAMICS UPVOTE WILL BE GIVEN. PLEASE WRITE THE COMPLETE SOLUTIONS LEGIBLY. SHOW THE STEP-BY-STEP PROCESS WITH SHORT COMMENT/EXPLANATION. ANSWER IN 3 DECIMAL PLACES. Note: Use values of MW, Cp, Cv, etc., from the Tables provided below.

An open system is often referred to as control volume, which is a properly selected region in space in which mass and energy can flow across the boundaries as figure 1.2. The boundary of a open thermodynamic system is called the control surface Across the Boundaries E = Yes F 0 = Yes w =Yes Control surface ass YES W CONTROL VOLUME energy YES Figure 1.2. A cooling/heating radiator is an example of such a system – give two more examples of such a system.

I need answer within 20 minutes please please with my best wishes

A solid steel cube is stored in a freezer, where the temperature is −20.0 ̊C. While the cube is in the freezer, you measure its side length (L) to be 1.75050 meters. The cube is then placed outside for a long time, so that the temperature of the cube reaches the temperature of the air outside. As a result, the side length increases to 1.75170 meters due to thermal expansion. The coefficient of linear expansion for steel is 12.0×10−6 ̊C−1. (a) What is the temperature of the air outside? Give your answer in degrees Celsius ( ̊C). (b) What is the volume of the cube when its temperature is 20.0 ̊C? Give your answer in cubic meters (m3).

This is a question from my problem sheet with the answers. i dont understand how to answer this question. Please use this book for the values: Thermodynamic and Transport Properties of Fluids by Rogersand Mayhew.

Give at least five (5) application of thermodynamics in real life that is can't be found on the internet. Briefly explain each application using different concepts, principles and/or theories in thermodynamics.
