Can silicon be a gas?
Sure, you just need to heat or pressurize it sufficiently. At 1 atm of pressure, elemental silicon boils at 2,357 degrees Celsius. At room temperature, though, silicon is solid.
If you wanted to know the the amount of heat needed to raise the temperature of 2 kg of steel by 10 degrees celsius what do you need to know about steel?
You need to know its specific heat.
Why copper is solid at 20 celsius?
Because 20C is *way* below its melting point, which is obvious - maybe you need a more detailed answer.
What does it mean to say that the specific heat capacity of water is greater than that of iron?
Heat capacity is the amount of heat needed to increase the temperature of an element (a given mass) by a temperature unit.Specific Heat Capacity is the amount of heat in Joulesneeded to heat 1kg of an element by 1 degree Kelvin.Joules per Kilogram KelvinIf the SHC of water is higher than that of iron, it means, you need more heat to increase the temperature of 1kg of water in 1 degree Celsius, than the heat you need to increase the temperature in 1 degree Celsius of the same mass of iron.P.S.A Celsius temperature difference is the same as a Kelvin temperature difference. In measuring SHC, we only need to focus on temperature difference rather than the temperature value. Add 273.15 to the Celsius measurement of the temperature to get the Kelvin temperature value.
What energy is needed to change a material from solid to liquid?
Heat energy, usually. However, some substances will change states under the influence of UV or other radiation.AnswerThe energy needed to change a material from a solid to a liquid is called the 'latent heat of fusion', or just the 'heat of fusion'. It is equal to the amount of energy or heat given off by the same material to change it from a liquid back into a solid.Each material has its own heat of fusion. Take solid water (ice) at 0o Celsius, the freezing point. Water's heat of fusion is 79.71 calories per gram. That means that you will need to add 79.71 calories of heat to each gram of ice (solid water) to turn it into liquid water. Interestingly, once that's done, the water will still be at 0o Celsius! The heat was used just to change the water's state from solid to liquid. Once the ice is liquid, then any more heat added will increase the temperature of the liquid, and each calorie of heat will increase the water's temperature about 1o Celsius.This is a similar concept to a material's 'heat of vaporization', which is the amount of energy required to change a liquid to a gas.The amount of heat necessary to change a substance from a solid to a liquid or vice versa is commonly called the heat of fusion. It is more properly known as the standard enthalpy of fusion, or also the latent heat of fusion, or the enthalpy change of fusion. The specific temperature at which the change occurs is defined as the melting point of that substance. A link can be found below.The amount of energy a substance must absorb in order to change from a solid to a liquid is the heat of fusion. A change in which a system absorbs energy from its surroundings is endothermic change.

Do you need to add or subtract heat make a solid into gas?
Add heat.
If you wanted to know the the amount of heat needed to raise the temperature of 2 kg of steel by 10 degrees celsius what do you need to know about steel?
You need to know its specific heat.
What equipment would you need to heat a small amount of solid strongly?
oven
What do you need to melt a solid in energy flow terms?
Melting is an exothermic process; we need heat for melting.
Can you turn a liquid into a solid by freezing it?
No, freezing changes a liquid to a solid. To change a solid to a liquid you need to apply heat. The change begins when the solid reaches its melting point.
What do you call a piece of metal used to hold and support glassware?
for test tube you will need a test tube holder , and for hot glassware you will need a crucible tongs. Enjoy
What would you do without Bunsen burner?
If you need to heat something: use an electric hot plate, water bath, or incubator. If you need a naked flame: light a match, lighter, or candle. If you need to work glassware: a butane lighter with a concentrated flame may work for small glassware (e.g. pipettes), for larger pieces you may need to go to a glassworking shop or find a Bunsen burner or forge.
What is HS code of mechanical glassware?
In order to accurately classify your mechanical glassware, we will need additional product information. The more you tell us about your mechanical glassware, the easier it will be for us to help you classify it.

Why do we need to clean or wash the glassware after using?
To get rid of germs.
