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.
Just with these expenses alone, we're already up to $2600 a year to own a dog. Which by-the-way, is way more than the average person's guess of $300 annually. Now let's factor in the average lifespan of a Miniature Schnauzer: At around 15 years....we're now spending $39,000 a year to own a dog! But wait, we have to go back and add the actual cost of the dog (we'll use $500 for this example) as well as any other one-time fees like:f you ask the average person who is about to go buy a dog, how much they think the annual cost of owning a dog is, they will most likely add the purchase price of the dog to an estimated amount they think it will cost to feed the dog, and that's it.
