Hi,
Hope you are doing well.
PART (a):
(i) Placing the thermometer in a room temperature water bath will cool its faster since the water has more specific heat capacity.
PART (b):
This method of heat transfer is known as Conduction.
PART (c):
It will take more time to cool from to .
Since is very close to room temperature, their temperature difference will be very small. So according to Newton's law of cooling we can say that, It will take more time to cool from to than from to .
Hope this helped for your studies. Keep learning. Have a good day.
Feel free to clear any doubts at the comment section.
Please don't forget
to give a thumbs up.
Thank you. :)

You pour 100 g of boiling water into a 3 kg cast-iron pot at room temperature (20°?). What will the water cool to?
14. Your thermometer, when calibrated reads 102˚C in boiling water and -1˚C in an ice bath. Explain how you would correct for your thermometer’s inaccuracy in each of the following cases. a. You wish to concentrate a sucrose solution so that it boils at 110˚C. b. You wish to record the correct boiling point of a liquid that boils when your thermometer reads 96˚C. c. You wish to record the correct freezing point of a solution that freezes when your...
Water entering a wet cooling tower at 35°C at a rate of 100 kg/s is cooled to 22°C in the cooling tower by air that enters the tower at 1 atm, 20°C, and 60% relative humidity and leaves saturated at 30°C. The makeup water of 22°C is supplied to the outlet to make the mass flow rate of the cool water the same as that at the inlet, see Figure Q5. Q.5Water entering a wet cooling tower at 35°C at...
Explain what is the purpose of the following reagents/procedural steps in the synthesis of acetaminophen by reacting p-aminophenol with acetic anhydride: a. Phosphoric acid b. Placing the reaction flask in warm water c. Purpose for placing crude product of acetaminophen in a 100 ml beaker with 20 ml of water, then heat it on a hot plate until crystals dissolves then let cool. Then having it in an ice bath for 20 min once crystals appeared. d. Drying product at...
can you please solve all three questions. TIA The boiling point of water at 1 atm is 100°C and the boiling point of ethanol at the same pressure is 78°C. Which one has the higher vapour pressure at a particular temperature? Select one: O They will have the same vapour pressure Ethanol O Water Check In this lab, you will determine the vapour pressure of water or ethanol (P) at various temperatures and use this data to find the enthalpy...
i dont understand why the molecular weight i calculated (42.012 g/mol) for my unknown liquid (acetone) is less than the actual molecular weight (58.08 g/mol). what errors could i have made in my lab that would account for the difference. Molecular Weight of a Volatile Liquid In this experiment, an amount of liquid more than sufficient to fill the flask when vaporized is placed in a flask of measured volume and mass. The flask is then heated in a boiling...

In this Diels-Alder reaction, what is the limiting reagent for this reaction? Please show work In this experiment, a Diels-Alder reaction will be performed to generate 4-cyclohexene- 1,2-dicarboxylic anhydride. The reaction occurs when 1,3-butadiene is combined with maleic anhydride and heated as shown below. Once the product has been isolated, the IR spectrum, melting point, and experimental yield can be determined. 5.- I111NI O Due to the inherent difficulties with the handling of gaseous 1,3-butadiene, it will be generated in...
PLEASE ANSWER ALL PARTS OF THE PROBLEM CORRECTLY. THANK YOU FOR YOUR HELP! 9:00 PM (10%) Problem 5: A constant-volume thermometer consists of a rigid bulb and a pressure gauge. To obtain accurate results, this thermometer must be calibrated at a known pressure and temperature. Once this is done, the bulb is sealed off from the atmosphere. The volume and number of moles of gas can no longer change and the temperature is calculated from the pressure measurement. 25% Part...
