Page 268 - It is hardly necessary to add, that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner Heat was excited and communicated in these experiments, except it be MOTION.
Page 337 - It is impossible for a selfacting machine, unaided by any external agency to convey heat from one body to another at a higher temperature, or heat cannot of itself pass from a colder to a warmer body.
Page 267 - Ib. of icecold water to boil) could have been furnished by so inconsiderable a quantity of metallic dust ? and this merely in consequence of a change of its capacity for Heat...
Page 302 - Explain why the specific heat of a gas at constant pressure is greater than the specific heat at constant volume.
Page 337 - It is impossible for a self-acting machine, unaided by any external agency, to convey heat from a body at a low to one at a higher temperature;" or " Heat cannot of itself (that is, without the performance of work by some external agency) pass from a cold to a warmer body.
Page 283 - ... the science of thermodynamics." When work is transformed into heat, or heat into work, the quantity of work is equivalent to the quantity of heat.
Page 431 - ... inch Ib. sec. units is -0012 and the latent heat of steam is 536. Find the temperature of the under side of the heating surface. Explain carefully why this is not the temperature of the furnace. 7. Define the thermal conductivity of a substance and describe some way of measuring it. 8. How many units of heat will be conducted in an hour through each square centimetre of an iron plate 0'02 cm. thick, its two sides being kept at the respective temperatures of 0°C. and 50° C., the mean conductivity...
Page 283 - With what velocity must a lead bullet at 50°C. strike against an obstacle in order that the heat produced by the arrest of its motion, if all produced within the bullet, might be just sufficient to melt it?
