Most metals are good conductors of heat and they are solids at room temperature. Mercury is the only one in liquid state at room temperature, and has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. This is the reason behind mercury and alcohol being used in thermometer. Some of the principles of the thermometer were known to Greek philosophers of two thousand years ago.
Veterinary/Medical costs: $160 â 670. The cost of spaying or neutering a dog is $50-200 depending on the size of the dog and whether there are health conditions that can complicate the surgery. A routine veterinary exam runs from $45-150. The cost of puppy vaccinations and boosters is $20-150.
When you take into account inflation and rising costs, if you bought a new puppy today, Sainsburyâs estimate the annual cost could easily rise by about 20 per cent to Â£1,418 during its life expectancy, which is on average 13 years. This would take the cost of owning a dog to nearly Â£18,500 in its lifetime.
