Answer #1

This is a quESTION based on ANAMOLOUS EXPANSION of water

water expands on cooling at 4degree centigrade and contracts on heating

if a tumbler of water at 4degee centigrade is heated it gains heat energy and temperature of water increases and the water expands over flows

if a tumbler of water at 4degree centigrade is heated is cooled then the temperature falls and water expands due to anamolous expansion . so water over flows.

so temperature of water filled in the tumbler initially is 4degree centigrade

⦁   Two identical containers A and B, filled with equal masses of 2 different liquids, initially at 20°C, are heated on a hot plate and both receive the same amount of heat. As a result, the temperature of liquid A is raised to 40°C and that of liquid B is raised to 80°C. If the liquids are now poured into a third, larger container and mixed, would their final temperature be lower, higher, or exactly equal to 60˚C? Explain your...

You place identical pots on the stove and heat them equally. Pot A contains 1.00 g of water; pot b contains 100 g of water. Both pots start out at 25 degrees C. a) If you heat both pots of water until they boiled, which pot will boil first? Why? b) When both pots are boiling, what is the temperature in pot A?

Two identical containers are open at the top and are connected at the bottom via a tube of negligible volume and a valve that is closed. Both containers are filled initially to the same height of 1.00 m, one with water, the other with mercury, as the drawing indicates. The valve is then opened. Water and mercury are immiscible. Determine the fluid level in the left container when equilibrium is reestablished.

Two pots are identical except that the flat bottom of one is aluminum, whereas that of the other is copper. Water in these pots is boiling away at 100.0 ˚C at the same rate. The temperature of the heating element on which the aluminum bottom is sitting is 156 ˚C. Assume that heat enters the water only through the bottoms of the pots and find the temperature of the heating element on which the copper bottom rests.

A two-meter long pipe filled with water is open at one end and closed at the other. You have at your disposal a tuning fork with a frequency of 250 Hz and a noise meter (a device to measure the intensity of a sound in decibel). Using the tuning fork, you lower the water level until you hear the first three resonances. The first, second, and third resonances are at 0.35m, 1.05m and 1.75m respectively. At the same time, your...

The Columbus Dispatch conducted a study. Two identical football, one filled with helium and one filled with ordinary air, were used. A casual observer was unable to detect a difference in the two footballs. A novice kicker was used to punt the footballs. A trial consisted of kicking both footballs in a random order. The kicker did not know which football he was kicking. The distance of each punt was recorded, then another trial was conducted. A total of 39...

Two identical resistors are connected in parallel across a 27-V battery, which supplies them with a total power of 6.9 W. While the battery is still connected, one of the resistors is heated so that its resistance doubles. The resistance of the other resistor remains unchanged. Find (a) the initial resistance of each resistor, and (b) the total power delivered to the resistors after one resistor has been heated.
