Why does the water in the earthenware container stop
boiling as soon as the pot is removed from the fire, and in the
metal vessel it boils for a while?
Out of earthenware pots and metal pots, specific heat capacities of earthen pots is less, so they can't keep heat absorbed in them while metal pots retain heat absorbed in them that's why water boiled in metal pots keep on boiling for a while after removing it from fire using heat retained in it while earthen pots do not retain heat in them so water stops boiling at once.

While boiling potatoes for dinner in salted water, the pot boils over and you notice that the flame on your gas burner turns bright yellow-orange. How would you explain the appearance of a color in the previously blue flame?
r is placed into a pot of boiling water. After 60 seconds in the pot, the thermometer reads 100° C and is removed. Which method would cool the thermometer the fastest? (1 pt) a. i. Placing the ermometer in a room-temperature water bath Exposing the thermometer to room-temperature air ii. (ifi) Exposing the thernometer to room-temperature air and an electric fan b. Name the heat transfer mechanism of the method you selected above. (I pt) c. Using the same cooling...
2) A student boils a metal block for 2 minutes and the temperature of the boiling water is 105.1 °C. the metal block has a mass of 250.42 g. The metal object is removed from the boiling water and submerged in 130.00 mL of water at 23.7 °C. The equilibrium temperature was 36.9 °C. a) Assuming no heat was lost to the surrounding, determine the specific heat capacity of the metal. (6 points) b) Calculate the percent error if the...
Water is in a pot on the stove boiling at constant temperature. The water is the system a. ∆U + ∆Ek = Q b. ∆U = -∆EP c. ∆U = Q d. ∆U + ∆Ek + ∆EP = Q-W e. W = Q A system in which does not allow heat to transfer across the system boundary (Q=0) is known as Adiabatic Transient Differential Stead state Differential The internal energy change of a system cannot be assumed to be zero...
A pot of water with 251 g of water is boiling. At 100oC how much energy (in kJ) will need to be added until all of the water converts to steam? ΔHvap = 40.7 kJ/mol
Problem 8.1 Saturated water is heated in a pot (cylindrical container) made out of 2 mm thick stainless steel 304. The pressure in the kitchen is 1 atm. The temperature of the heated bottom (20 cm diameter disk) is Tdisk Calculate the heat flux for Tdisk-| 01 C, 103 C, 105 C, I 10 C, I 20 C 150 C. Find the point of interception between natural convection and boiling. Plot a the log q vs. log dT a) b)...
stone boiling is a method of cooking that has been used throughout the world, especially before the introduction of heat-resistant vessels(such as ceramics). It involves dropping "red- hot" stones into a container of water it boils. Suppose a 0.4 kg stone at 300 C is dropped into a vessel containing 10 litres of water at 20 C. Neglecting heat transfer to the container, what is the final temperature of the stone and water? [ Take the specific heat of this...
You pour 100 g of boiling water into a 3 kg cast-iron pot at room temperature (20°?). What will the water cool to?
why does boiling water turn to snow when thrown in the air on a cold day, but cool water does not?
why doesn’t the temperature on the thermometer increase as soon as boiling begins in the flask during a simple distillation?
