What element is used in atomic clocks and photocells?
Cesium is commonly used in atomic clocks due to its high accuracy in timekeeping. Photocells often use silicon as the element at their core due to its semiconducting properties, which allow it to efficiently convert light into electricity.
What causes the oven element to burn out?
The oven element can burn out due to factors such as overuse, high temperatures, physical damage, or manufacturing defects.
How does a thermeter work?
A thermometer works by measuring temperature using a temperature-sensing element, such as mercury or a thermocouple. When the element is exposed to a change in temperature, it expands or contracts, producing a corresponding change in length that is displayed on a scale. The scale provides a numerical value to represent the temperature.
As temperature increase pressure remaining constant the half life of a radioactive element?
Increases. An increase in temperature typically increases the rate of chemical reactions, including radioactive decay. This means that at higher temperatures, the rate of decay of a radioactive element will be faster, resulting in a shorter half-life.
The element in a thermostat that is sensitive to temperature changes is what?
The element in a thermostat that is sensitive to temperature changes is typically a bimetallic strip. This strip is made up of two different metals that expand and contract at different rates in response to temperature variations, causing the strip to bend and activate the thermostat's switch.
What element is used in atomic clocks and photocells?
Cesium is commonly used in atomic clocks due to its high accuracy in timekeeping. Photocells often use silicon as the element at their core due to its semiconducting properties, which allow it to efficiently convert light into electricity.
What element is used to make light sensitive photocells electric eyes and fire alarms?
Selenium
What element is found in photocells?
Silicon is commonly found in photocells, also known as photovoltaic cells, because it exhibits properties that make it efficient for converting light into electricity. Other elements, such as indium, gallium, and selenium, can also be found in some types of photocells to enhance their performance.
What element is used in high temperature thermometers?
Platinum is often used in high temperature thermometers due to its ability to maintain stability and accuracy at elevated temperatures.
Is bromine the element brittle?
No, Bromine is not brittle at room temperature, as Bromine is one of only two elements in the Periodic Table that is a liquid at room temperature.
What is a ptc heating element?
A PTC (Positive Temperature Coefficient) heating element is a type of heating element that increases resistance as temperature rises. This characteristic allows the heating element to self-regulate its temperature, providing a safety feature to prevent overheating. PTC heating elements are commonly used in appliances such as hair dryers, irons, and space heaters.
What gas boils at 4800 degrees?
This would not be gas, these boil at temperatures below room temperature. Such a high temperature indicates a compound such as a carbide, the highest melting element is tungsten.
What element remains solid in warm and remains liquid in cold temperatures?
There is no such element as this is physically possible. The liquid state is only achieved when the temperature has reached the melting point of the material. And, the melting point is, by definition, at a higher temperature than the freezing point. However, there are substances that are liquids in cold temperatures (many oils) as well as substances that are solids in warm temperatures (most metals); but this does not mean that the oils do not freeze and the metals do not melt.
What is helium at room temperature?
Helium is a gas at room temperature.
When is helium temperature?
The element helium can exist over a very wide range of temperatures. Helium is notable for having the lowest boiling point of any element. Liquid helium is exceptionally cold.
What temperature do frog live in?
Frogs hibernate when the temperature is less than 10 degress Celsius. They can hibernate at temperatures of -7 degrees Celsius at most and can survive in desert temperatures. The highest desert temperature is 49 degrees Celsius, so frogs can probably survive in that temperature. They have a bladder that stores water for them when in HI temperature so they can survive there. They have an ANTIFREEZE chemical element in their body so they can survive in LOW temperatures.
What element is used to make light sensitive photo cells for camera electric eyes and fire alarms?
It used to be Selenium, but modern photocells use silicon (Si).
