What substance melts at 20 degrees what type of structure?
Water melts at 0 degrees Celsius, not 20 degrees. Water has a hexagonal close-packed structure when it is in solid form.
What is the connection between a metalloid and semiconductor?
The connection between a metalloid and a semiconductor is that metalloids are used in electronics as semiconductors. A semiconductor doesn't conduct electricity as well as a metal, but does conduct electricity better than a nonmetal.
Do other substances freeze at the same temperature as water?
Different substances freeze at different temperatures. The freezing point of a substance depends on its chemical composition and structure. Water, for example, freezes at 0 degrees Celsius (32 degrees Fahrenheit), but substances like mercury freeze at -39 degrees Celsius (-38 degrees Fahrenheit).
What happens when light passes through a substance near 0 degrees Kelvin?
When light passes through a substance near 0 degrees Kelvin, it bends and becomes deformed.
What substance in the table is a liquid at 105 degrees?
To determine which substance in the table is a liquid at 105 degrees, you would need to know the melting and boiling points of the substances listed. A substance that has a melting point below 105 degrees and a boiling point above 105 degrees would remain in liquid form at that temperature. Please provide the specific substances for a more accurate answer.
Can iron conduct electricity as a liquid?
Iron melts and becomes liquid at an 2800 degrees Fahrenheit. It can still conduct electricity, but, like all conductors, it conducts better at lower temperatures.
What substance melts at 20 degrees what type of structure?
Water melts at 0 degrees Celsius, not 20 degrees. Water has a hexagonal close-packed structure when it is in solid form.
Is the ability to conduct electricity a intensive or extensive physical property?
The ability to conduct electricity is an intensive physical property because it does not depend on the amount of the substance present. Different materials will have varying degrees of conductivity regardless of the quantity.
What nonmetals conducts electricity?
Various non-metals can conduct electricity, such as graphite. Graphite is an allotrope of carbon, and it has one electron per carbon atom that is delocalized and not involved in chemical bonding, thus it can carry electric charges. Other non-metallic materials like semi-conductors can also conduct electricity to various degrees. Molten and aqueous ionic compounds like sodium chloride also conduct electricity.
What is the connection between a metalloid and semiconductor?
The connection between a metalloid and a semiconductor is that metalloids are used in electronics as semiconductors. A semiconductor doesn't conduct electricity as well as a metal, but does conduct electricity better than a nonmetal.
Why ionic solids cannot conduct electricity in the solid state?
Electric current is moving charges. Solid ionic compounds do not conduct electricity because the charged ions are locked into place, causing the melting points of ionic compounds to be very high-often well above 300 degrees C. Vvlake11
What temperature does every pure substance boil at?
The boiling temperature of a pure substance is unique and specific to that substance. It is determined by its molecular structure and strength of intermolecular forces. This characteristic boiling temperature is referred to as the substance's normal boiling point.
Can you be electrocuted if not touching a solid surface?
Yes. All sorts of material conduct electricity to varying degrees, including solids, liquids and gasses. Also, the voltage is critical. Extremely high voltage electricity can arc for tens to hundreds of meters, such as in a high power Tesla coil or naturally occurring electricity.
How many degrees is the melting point?
The melting point of a substance varies according to the properties of that substance
What is a substance that boils at 100 degree and freezes at 0 degrees?
Water is a substance that boils at 100 degrees Celsius and freezes at 0 degrees Celsius.
What state is a substance in at 1 ATM and -50 degrees Celsius?
The state of a substance at 1 ATM and -50 degrees Celsius would depend on the substance. For most substances, at -50 degrees Celsius and 1 ATM pressure, they would typically be in a solid state.
Do other substances freeze at the same temperature as water?
Different substances freeze at different temperatures. The freezing point of a substance depends on its chemical composition and structure. Water, for example, freezes at 0 degrees Celsius (32 degrees Fahrenheit), but substances like mercury freeze at -39 degrees Celsius (-38 degrees Fahrenheit).
