What is polonium's state at 20 degrees?
At room temperature, polonium is a solid. However, at elevated temperatures, it may be turned into a liquid or even a gas (at very high temperatures). Polonium is a metalloid, having properties between metals and nonmetals.
The element in a thermostat that is sensitive to temperature changes is what?
In a car thermostat the element is wax
Is temperature the total gravitational potential energy of an element?
yes
What is the normal temperature for xenon?
The normal temperature is 20 deg C - irrespective of the element or compound under consideration.
What is the use of a bimetallic thermometer?
A bimetallic element is used in order to react it from various temperature that will indicated the temperature of an object or body.
What element is found in photocells?
Rubidium and cesium
What element is used to make light sensitive photocells electric eyes and fire alarms?
Selenium
What is a ptc heating element?
Positive temperature coefficient heating element. Resistivity grow larger with higher temperatures so the heating element should be self regulating.
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.
How can an element have freezing point at 200 degrees F?
an element's freezing point is the temperature at which the element becomes solid. some element's don't melt til heated to very high temperatures, and could therefore have a freezing point in the 100s of degrees.
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.
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 happens to the resistance of the bulb as the current passing through it increases?
Yes but very slightly,because temperature coefficient of bulb element is very low.
What element measures temperature?
Any element can be used to measure temperature.
The Element Oxygen Is A Gas That Make Up About 20 Percent Of Earth's Atmosphere Oxygen Is Also Most Abundant Element I Earth's Crust Yet Earth's Crust Is Not A Gas Explain This Apparent Conflict?
What conflict? Elemental oxygen is a gas at ordinary temperatures (around 300K). Water is about 90% oxygen by mass, but it's a liquid at the same temperature. Nearly all metal oxides are solids at that temperature. The physical state of an element at a given temperature has almost no relationship to the physical state of compounds containing that element at the same temperature.
What element will withstand low temperatures?
everything
