"Three temperature scales compared against one another." -Comstock 1850

Temperature Scale

"Three temperature scales compared against one another." -Comstock 1850

Shows the differences between the Centigrade and absolute (Kelvin) temperature scales at the boiling point of water, room temperature, freezing point of water, boiling point of hydrogen and absolute zero.

"Tenacity is that property of matter by virtue of which some bodies resist a force tending to pull their particles asunder Its measure is the ratio between the breaking weight and the area of the cross section of the body broken. It varies with different substances, with the form of the body, with the temperature, and with the duration of the pull." -Avery 1895

Testing for Tenacity

"Tenacity is that property of matter by virtue of which some bodies resist a force tending to pull their…

"Thermometers showing the corresponding points for water's freezing and boiling." -Avery 1895

Fahrenheit and Celcius scale Thermometers

"Thermometers showing the corresponding points for water's freezing and boiling." -Avery 1895

"Tyndall's experiment illustrating the production of heat by friction. The wheel is rotated and heat is produced [by friction] that heats the water in the end of the brass tube, which causes the water to boil, producing steam which pops off the cork." -Hawkins, 1917

"Over the upper end of a cylindrical receiver, tie tightly a wet bladder or sheet of writing paper and allow it to dry. Then exhaust the air. The bladder will be forced inward, bursting with a loud noise. Replace the bladder with a thin sheet of india-rubber. Exhaust the air. The rubber sheet will be pressed inward, and nearly cover the inner surface of the receiver." -Avery 1895

Vacuum

"A cubic centimeter of water weighs 1 gram." — Avery, 1895

Water and scale

"A cubic centimeter of water weighs 1 gram." — Avery, 1895

"When any liquid is placed in one or more of several vessels communicating with each other, it will not come to rest until it stands at the same height inall of thw vessels. This principle is emobodied in the familiar expression 'Water seeks its level.' the principle is illustrated, on a large scale, in the system of pipes by which water is distributed in cities." -Avery 1895

Water Level in Multiple Connected Vessels

"Therefore, the small quantity in the spout balances the large quantity in the pot, or presses with the same force downwards, as that in the body of the pot presses upwards." -Comstock 1850

Water Pressure

"Therefore, the small quantity in the spout balances the large quantity in the pot, or presses with…

"If a vessel be filled with water, and three apertures be made in its sie at E F G, the fluid will be thrown out in jets, falling to the earth in the curved lines shown." -Comstock 1850

Water Velocity and Gravity

"If a vessel be filled with water, and three apertures be made in its sie at E F G, the fluid will be…

"Take a piece of ivory, or any other substance that will sink in water, and weigh it accurately in the usual manner; then suspend it by a thread, or hair, in the empty cup a, and balance it. Now pour water into the cup, and it will be found that the suspended body will lose a part of its weight, so that a certain number of grains must be taken from the opposite scale, in order to make the scales balance as before the water was poured in. The number of grains taken from the opposite scale, show the weight of a quantity of water equal to the bulk of the body so suspended." —Comstock, 1850
