Why isn't the thermometer's bulb made of metal?
Metal has a high co-efficient of expansion and would show the wrong temperature by expanding to give more volume in relation to glass on heating and opposite effect when cooling
What is in Cooling Fins on A Radiator?
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
What happens when hot metal is cooling?
it cools down
What will happen energetically to a cup of boiling hot water that is added to a cup containing a cold piece of metal?
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
Why are central heating radiators made of metal?
radiators need to dissapate heat, and metal can dissapate heat quickly
What is the process of rapid cooling of heated metal?
Quenching , or quench hardeningis the process of rapidly cooling hot metal in a cold liquid. Its a process in which iron alloys and steel are hardened. This is done by heating the material to a certain temperature, and then cooling it rapidly in a cold liquid, usually water.
What is the process of rapidly cooling hot metal in a cold liquid called?
quenching
Fuel source that was used in china that impressed Marco?
the heating and then quick cooling of the metal adamantium
Why do you use mercury in thermometers if it is not a good conductor of heat?
- mercury is a liquid metal - cooling and heating are easy reversible - cooling and heating are rapid - the relation between the temperature and the thermal expansion of mercury is linear
What does the term annealing mean?
It's heat treatment. By heating and cooling a metal under very controlled circumstances the properties of the metal can be improved.
Which metal expands on cooling and contracts on heating?
Bizmuth is a heavy metal that expands on cooling and contracts on heating. it is used for making lead free ammunition, especially for shotgun rounds and airgun pellets as it is considered non-toxic. It is also used in the glass making industry for making 'float' glass sheets.
What is an annealer?
An annealer is a device or process which anneals - hardens by the process of greatly heating an object before cooling it slowly to render it less brittle.
Why does metal become more brittle after being heated then cooled?
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
How much does it cost to replace your 90000 BTU furnace?
It depends on the efficiency you are looking for and the metal work that needs to be done. Contact heating and cooling companies to get estimates.
Why isn't the thermometer's bulb made of metal?
Metal has a high co-efficient of expansion and would show the wrong temperature by expanding to give more volume in relation to glass on heating and opposite effect when cooling
Does Thermal Transient Testing degrade the bridge wire?
If Thermal Transient Testing involves heating and then cooling a metal wire then the average light (incandescent) bulb is a good answer.
Does heating metal affect its strength after it has cooled?
Yes, always. the temperature of the heat, time for which it is applied, cooling methods and metal itself all determine how its tensional, torsional and compressional strength will be affected (stronger or weaker, and by what factor).
