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.
Dog Food: $150 â 500. The cost of your dogâs food will depend on his size and what you feed him. The bigger the dog, the more he eats, and premium dog food is more expensive than off-brand kibble. You can save money with a generic food, but it could be at the expense of your dogâs health.
Most pet owners calculate the price of the food and add it to the cost of the dog and figure that they can afford it regardless of their budget. The reality is that very few people have any idea how much owning a dog really costs and grossly underestimate it.he cost of a guaranteed healthy, well-bred $1000 puppy is a fraction of what it will cost to own that dog for 12 years. A poorly bred dog with bad hips, allergies, and a not so bright disposition will end up costing you thousands more in medical bills not to mention hours of frustration and disappointment.
