The element will always use full available power if you are starting from a cool oven. (Some high end ovens wont do it this way). However if you want to go from say 350 to 400 the oven will usually get hotter faster if you set it to 500 (or broil) first. Then turn it down at 400. This will not work on all ovens.
Idea: you can tell the temperature of the oven by turning knob down until light goes off. at that point on the dial you can read the current temperature of the oven. Warning - the oven will turn the elements off with this method and may wear them out because of too fast cooling and heating. They are made for that but can still shorten life. be as quick as you can so off time is as short as possible.
You are confused between speed of sound and pitch. The speed of sound will remain constant at specific temperature and the medium. Since 256 Hz is a higher pitch, it will be shriller. Hope that helps :D
Room temperature water boils faster than cold water because it is closer to the boiling point, requiring less energy to reach that point. Cold water must first be heated to room temperature before it can reach the boiling point, delaying the process.
The ideal temperature for a perfectly cooked steak is typically around 130-135F for medium-rare, 140-145F for medium, and 160F for well-done.
For a medium-well steak, the recommended cooking time is about 4-5 minutes per side on a grill or in a pan over medium-high heat. The internal temperature should reach around 150-155F (65-68C).
The temperature of the water and the something will reach an equillibrium somewhere between the two and eventually both will reach room temperature. Time depends on the temperature and mass of the something and the temperature and volume of the water.
There's less water, it takes less time for all if it to reach freezing temperature.
To ensure your burgers are cooked to a medium well temperature, use a meat thermometer to check the internal temperature. Cook the burgers until they reach 150-155F (65-68C). This will ensure they are safe to eat while still retaining some juiciness.
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
Covering a pot can make it boil faster because it traps heat and prevents it from escaping, which helps the water reach boiling temperature more quickly.
The correct internal temperature for a beef rib roast is 135 degrees for medium rare. You should take it out of the oven when it reaches this temperature. Once it stands for abit, outside the oven, the internal temperature will reach 145 degrees.
Always try simple first...thermostat is probably stuck open...cheap and easy replacement.
When a liquid is heated, its temperature will increase. As the temperature rises, the molecules in the liquid will gain more energy and move faster. Eventually, if the temperature is high enough, the liquid will reach its boiling point and turn into a gas.
