Why does hot water steam when it's thrown out of a cup in a cold temperature?
When hot water is exposed to cold air, the temperature difference causes the water to release heat rapidly, turning it into steam. This rapid evaporation creates the visible steam cloud that you see when hot water is thrown out of a cup in a cold temperature.
How does heat flow from hot to cold, and what factors influence this process?
Heat flows from hot to cold due to the natural tendency of energy to disperse and reach equilibrium. Factors that influence this process include the temperature difference between the two objects, the material properties of the objects, and the presence of any insulating materials.
Why do you feel hot and cold?
Feeling hot or cold is usually a result of your body's attempts to regulate its internal temperature. When you're hot, your blood vessels dilate to release heat, and when you're cold, they constrict to conserve heat. Other factors like illness, environmental temperature, and hormonal changes can also influence these sensations.
Which factor most determines how hot or clod something feels you touch it?
The main factor that determines how hot or cold something feels when you touch it is its temperature relative to your skin temperature. If the object is warmer than your skin, it will feel hot, and if it is cooler than your skin, it will feel cold. Other factors like thermal conductivity and surface area can also influence the sensation.
Why does steam come off the body after a hot shower?
When hot water hits the skin, it causes the water on the skin to evaporate quickly, creating steam. This is because the heat from the water increases the temperature of the water on the skin, causing it to turn into vapor.
How hot does methane burn and what factors influence its combustion temperature?
Methane burns at a temperature of around 1,960 degrees Celsius (3,560 degrees Fahrenheit). Factors that influence its combustion temperature include the amount of oxygen present, the pressure of the environment, and the efficiency of the combustion process.
How hot does oxygen burn and what are the factors that influence its combustion temperature?
Oxygen itself does not burn, but it supports combustion. The temperature at which oxygen supports combustion varies depending on the material burning. Factors that influence combustion temperature include the type of material, the amount of oxygen present, and the efficiency of the combustion process.
How hot can steam get?
The temperature of steam depends on the pressure of the system. Higher pressure steam can get super hot. Steam at atm is around 212 degree F, like boiling water.

How hot does a fire burn and what factors can influence its temperature?
A fire can burn at temperatures ranging from 600 to 1200 degrees Celsius (1112 to 2192 degrees Fahrenheit). Factors that can influence the temperature of a fire include the type of fuel being burned, the amount of oxygen available, and the presence of any accelerants or chemicals.
How hot can coal burn and what factors influence its maximum temperature?
Coal can burn at temperatures up to 3,500 degrees Fahrenheit. The maximum temperature is influenced by factors such as the type of coal, the amount of oxygen available for combustion, and the efficiency of the burning process.
What temperature does hot water changes to a new form?
Hot water changes to a new form, steam, when it reaches its boiling point of 100 degrees Celsius (212 degrees Fahrenheit). At this temperature, water vaporizes and transforms into steam, which is the gaseous phase of water.
How hot can wood burn and what factors influence its combustion temperature?
Wood can burn at temperatures ranging from 600 to 900 degrees Celsius. The combustion temperature of wood is influenced by factors such as the type of wood, moisture content, airflow, and the presence of other materials like accelerants.
What temperature should the water be maintained at to hold steam food items?
To hold steam food items, the water temperature should be maintained at a gentle simmer, around 180-190°F (82-88°C). This temperature is hot enough to generate steam for heating the food but not too hot to evaporate the water quickly or burn the food being steamed.
How hot is hot springs water?
It is often in excess of 100° F, or sometimes even close to boiling temperature. It is not that is is the volance steam
