Oh come one -_-''
Its obvious
Signs that water is boiling include bubbles rising to the surface rapidly, steam coming off the surface of the water, and the water appearing to be in a constant motion.
Three signs of physical change are change in shape, change in size, and change in color.
To safely reuse a heating pad after boiling it, make sure it has cooled down completely before using it again. Check for any signs of damage or wear and tear before applying it to your body. It is also important to follow the manufacturer's instructions for proper care and maintenance of the heating pad.
Helium is a colorless, odorless, and tasteless noble gas that is lighter than air, commonly used in balloons and airships. Neon is another noble gas that is red-orange in color when used in gas-discharge lamps, often seen in neon signs. They differ in their chemical properties and physical characteristics, with helium having a lower boiling and melting point compared to neon.
Corrugated signs are commonly used for temporary outdoor advertising or informational purposes, such as real estate signs, event promotions, political campaigns, or construction site notifications. They are lightweight, durable, and cost-effective, making them ideal for short-term messaging needs.

It's not a chemical change because the only the temperature and phase changes. The properties may be altered somewhat, but it the same chemical compound. No atomic bonds are broken or formed, there are no new substances formed, and none of the signs that indicate a chemical change are present. Some of the water is changing from a liquid to a gaseous state, and can be returned to a liquid state, unchanged, by cooling it.
red liquid
About 27 K, but you should be more accurate than that. If your school, science department, or library has a copy of the CRC Handbook of Chemistry and Physics - and one of these should - look in "Physical Constants of Inorganic Compounds" to find information like this.
Yes, you can eat an egg that cracked while boiling as long as it was cooked thoroughly and there are no signs of spoilage.
Diagnosis-KAD
There's a bit more than 3. gas -> liquid (condensation) liquid -> gas (evaporation) liquid -> solid (freezing) solid -> liquid (melting) solid -> gas (sublimation) gas -> solid (deposition) gas -> plasma (ionozation) Plasma -> gas (deionozation)
solid,liquid,or gas
Yes or it may be a sign of hormonal imbalance
All signs point to yes.
Trust what feels right... =)
All signs point to yes.
