I need help with thermodynamics

Hello I have two pictures with some questions Id like to get answers to! Short and great explanations please thank you !

Consider an introductory thermodynamics class experiment used to demonstrate phase change phenomena. A beaker of water is heated, and its temperature measured over time to establish the temperature at which boiling occurs. The results, shown in the Figure below, are for three separate tests conducted on different days by different student groups using the same equipment and method. Why might the data from three seemingly identical tests show different results? Temperature (°C) 101 100 99 98 97 96 95 94 1 2 3 4 Time (min) 5 Boiling region 100.3 100.1 99.8 Boiling point results Test 1 (762 mm Hg) Test 2 (754 mm Hg) Test 3 (767 mm Hg) 6 7

Question 1) Calculate how much energy (J) is required to heat up a pot containing 500. g of water from 23.0 °C to its boiling point of 100.0 °C (specific heat of water = 4.184 J/g°C). Question 2) An unknown solid object with a mass of 35.0 g was heated to 100.0 °C and transferred to a calorimeter containing 50.0 g of water at 23.0 °C. After thermal equilibrium was reached, the temperature inside the calorimeter was 26.5 °C. Calculate the specific heat of the unknown solid (specific heat of water = 4.184 J/g°C).

Moving to another question will save this response. estion 46 What is the mass of a body in grams if it has a kinetic energy of 94.6N-m when moving at 2.25m/s? →→ Moving to another question will save this response. OLO L

THERMODYNAMICS: Mollier Diagram: Steam Table Using the Steam Table below, find Δhf and Δhg in BTU/lbm and Δsf and Δsg in kJ/kgm-K and for the following parameters: P1 = 9.5 kgf/cm2  P2 = 15 kgf/cm2 With step by step explanation pls NOTE: This table uses SI unit as stated below: Pressure: MPa Temperature: °C Internal Energy and Enthalpy: kJ/kgm Entropy: kJ/kgm-K

Thermodynamics Please READ THE PROBLEM! I’m tired of posting the same problem over and over. please Read. This is what the asking for please: -1. sketch and label all your answers on the nozzle -2. Sketch and label all your answers on the process on a P-V diagram.... Thank you

P-4 Please I need help with this question needed a very clear and step-by-step explanation and needed with clear handwriting please, will be really appreciated your help.

What are the volumes of two chambers seperated by a piston wall that allows heat exchange but the system as a whole is isolated? The wall is initially fixed but then is loosed to move. How do you find the volumes of both chambers once equilibrium is reached? Each chamber is filled with a different, single-atom gas. I am given an initial mol, temperature, and pressure of each chamber.

I need help with this before tomorrow’s exam if I can get all needed calculations please

Q1 please

1. The development of thermodynamics since the 17th century, which was pioneered by the invention of the steam engine in England, and was followed by thermodynamic scientists such as Willian Rankine, Rudolph Clausius, and Lord Kelvin in the 19th century. explain what the findings or theories of the 3 inventors are! Please answer fast max 25-30.minutes thank u

please show work and formulas so that i may learn the process correctly. if you use a table please mention which table was used. thank you so much. 2. Fill in the blank cells of this table: T( C) P(kPa) u(kJ/kg) Phase description 175 2524.5 325 4000 325 Saturated liquid

THERMODYNAMICS TOPIC: FIRST LAW OF THERMO/THERMODYNAMIC SYSTEM   PLEASE ANSWER COMPLETELY THE QUESTION IN HANDWRITING AND SUPPORT YOUR SOLUTION WITH DIAGRAMS.   THANK YOU

Suppose there are two identical gas cylinders. One contains the monatomic gas krypton (Kr), and the other contains an equal mass of the monatomic gas radon (Rn). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEr /KERN of the average kinetic energy of an atom of krypton to the average kinetic energy of an atom of radon. The answer should be a value.

Hello tutors, help me. Just answer "Let Us Try"

Please make a detailed explanation of the step-by-step process. If it's possible to have a diagram, it will be much appreciated. Thank you!
