Surface tension, place a drop of detergent on the water and it breaks the meniscus allowing the water to flow away. Also the cohesion makes the water molecules stay together. It is not because of the ridge.
There are approximately 18,750 pennies in a 5-gallon water bottle.
Pennies weigh about 2.5 grams each. There are roughly 181 pennies in a pound and 2,381 pennies in a gallon. So, a 1 gallon water jug filled with pennies would weigh approximately 9.5 pounds.
The properties of water that allowed pennies to continue to be added to the glass are surface tension and cohesion. Surface tension creates a "skin" on the surface of the water, allowing the pennies to sit on top without sinking. Cohesion is the ability of water molecules to stick together, helping to support the weight of the pennies as they are added.
No, water is neutral. It has no acid in it whatsoever.
The number of pennies needed to overflow a glass of water depends on the size of the glass and the amount of water it contains. A standard glass can hold around 250-300 milliliters of water, and a penny weighs about 2.5 grams. In general, it would take several dozen to over a hundred pennies to cause the water to overflow, depending on how full the glass is and the displacement of the pennies.
Yes, dish soap can be effective in cleaning pennies. Soak the pennies in a mixture of dish soap and warm water, then gently scrub them with a soft brush or cloth to remove dirt and grime. Rinse the pennies thoroughly with water and pat them dry to reveal their shine.
Roughly $320 worth, that's 32,000 pennies.
6 liters of water weigh approximately 6000 grams. A penny weighs about 2.5 grams. So, to find how many pennies have the same mass as 6 liters of water, you would divide 6000 grams by 2.5 grams per penny, which is 2400 pennies.
The density of copper is 8.94 g/cm3. This can be calculated by dividing the total mass of the pennies (36.93 g) by the total volume they displace (4.13 cm3). This gives the density of copper as 8.94 g/cm3.
The pennies will corode.

i tink it would take about maybe estimate of 10,000 pennies i tink it would take about maybe estimate of 10,000 pennies
