Why aluminum can store more heat than iron?
yes
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.
Is fuel a liquid?
What are two substances that are needed for iron to rust
What are the raw materials needed for making iron?
iron no other materials are needed
What is state of iron at room temperature?
solid
Where does the energy needed to melt the iron come from?
The energy comes from the heat to melt the iron
Water requires more energy than an equal mass of iron for its temperature to increase by a given amount because water has a greater?
Water has a greater specific heat capacity.
Does iron keep things cold?
No, it takes a liw amount of heat to be able to heat iron up. Meaning that if iron was outside, the iron would heat up whatever object it has inside of it relatively quickly. If you want to get into specifics, iron has a low specific heat, so a low amount of energy is needed in order for temperature to change (energy is measured in heat [juoles])
How much energy per kg would it take to vapourise iron in Earth's core?
At standard pressure and temperature it takes about 6 Mj to vaporize one kg of iron. The high pressure at the core of the earth makes the central part solid and would probably increas the energy needed for vaporization.
How much energy is needed to melt 1 metric ton of iron?
1 GAJILLION
Why is hot iron red?
The elements inside the hot iron are energetic and some of that energy is released to its environment. The energy is released as photons at a certain frequency for each temperature of the hot iron. Energy at the frequency you are talking about is interpreted by the mind as the color red. If the hot iron were even hotter it might look like a more pale red. At a higher temperature yet it might look quite white.

yes
How can you transform electrical energy into thermal energy?
Yes, any time a current passes through a wire, part of the electricity will be converted into heat. This is used in a lightbulb (a small part of the heat then gets converted into light), in a shower, in an iron (for ironing your clothes), and others.AnswerThe term, 'thermal energy' is obsolete, having been replaced by the term, 'internal energy'. Yes, you can convert electrical energy into internal energy. That's what happens, for example, when you boil a kettle. The process of converting one form of energy into another is called 'work', so the kettle is doing work whenever it converts electrical energy into the water and increasing its internal energy. An increase in internal energy is accompanied by an increase in temperature. Whenever the temperature of the water exceeds the surrounding temperature, energy is lost to the surroundings through heat transfer. Heat is a process defined as energy in transit from a higher temperature to a lower temperature.

What is Iron needed for?
iron is needed for healthy blood
How much energy is required to raise the temperature of 3 kg of iron?
Q = 3 000 . 0,444 . ΔT (joules)ΔT is the difference of temperature.
What is the difference between temperature and internal energy?
Temperature is the degree of hotness. So, if you have say 1kg or iron and you put 100 calories of heat into it, and do them same to a 2kg lump of iron, the first one will become hotter than the second, although they will both contain the same amount of heat. This heat is part of the internal energy of the iron lumps.
