Joules apparatus for determining the mechanical equivalent of heat A vessel of water oil or mercury encloses vanes attached to a spindle Cord is wound round the cylinder and drum The weight descending against the scale rotates the spindle and vanes Raising and lowering the weight raises the temperature of the fluid From the rise in temperature and the distance travelled the energy used can be calculated British physicist James Prescott Joule determined the mechanical equivalent of heat The unit of energy called the joule is named after him
This giclée print delivers a vivid image with maximum color accuracy and exceptional resolution. The standard for museums and galleries around the world, giclée is a printing process where millions of ink droplets are “sprayed” onto high-quality paper. With the great degree of detail and smooth transitions of color gradients, giclée prints appear much more realistic than other reproduction prints. The high-quality paper (235 gsm) is acid free with a smooth surface.
