A piece of iron and a cup of water both ahave the same temperature If they are heated so the thermal engergy of each doubles?
If the thermal energy of the iron and water doubles, then the temperature of both substances will also increase. Iron has a much higher specific heat capacity compared to water, so the increase in temperature will be more significant for the water than for the iron. However, both substances will experience the same increase in thermal energy.
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.
Why was the rise in temperature obtained with zinc and copper sulfate nit much high that the rise in temperature obtained with iron and copper sulfate?
The difference in temperature rise between zinc and iron with copper sulfate is due to their differing reactivities. Iron is more reactive than zinc, so it releases more energy when reacting with copper sulfate. This higher reactivity results in a greater increase in temperature during the reaction.
What type of energy has been transferred when an iron pan is placed on a copper burner?
When an iron pan is placed on a copper burner, heat energy is transferred from the burner to the pan through conduction. The copper burner transfers its thermal energy to the iron pan, causing it to heat up and eventually reach the same temperature as the burner.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.

What Type of energy transformation occur in an iron?
When an iron is heated, the electrical energy is transformed into thermal energy. The atoms in the iron vibrate faster and collide with one another, leading to an increase in temperature.
How much energy is needed to increase the temperature of 100kg of iron by 40 degrees?
The specific heat capacity of iron is about 0.45 J/g°C. To calculate the energy required to increase the temperature of 100kg of iron by 40 degrees, we first convert kg to grams: 100 kg = 100,000 g. Then we use the formula: Energy = mass x specific heat capacity x temperature change. Therefore, Energy = 100,000g x 0.45 J/g°C x 40°C = 1,800,000 Joules or 1.8 Megajoules.
Where does the energy needed to melt the iron come from?
The energy needed to melt iron typically comes from heating the iron to its melting point, which requires input of heat energy. This heat energy can be created by burning fuels, using electric resistance, or other heat sources that can raise the temperature of the iron to the point where it transitions from a solid to a liquid state.
What causes the phases change when solid iron melts into liquid iron?
The phase change from solid iron to liquid iron occurs due to the increase in temperature, which imparts enough energy to the iron atoms to overcome the forces holding them in a rigid solid structure. As the temperature rises, the atoms gain enough kinetic energy to break free from their fixed positions and move more freely, causing the solid iron to transition into a liquid state.

Why iron thermally expanded?
Iron expands thermally due to the increase in kinetic energy of its atoms as temperature rises. When heated, the atoms vibrate more vigorously and move apart, leading to an increase in the material's volume. This thermal expansion occurs in all materials, but the extent of expansion varies depending on the material's properties. In iron, this phenomenon is typically characterized by its coefficient of thermal expansion, which quantifies how much it expands per degree of temperature increase.
How does the iron rod heat up?
When an iron rod is subjected to heat energy, the atoms within the rod start vibrating more rapidly, which results in an increase in temperature. This increased vibration causes the rod to heat up as the kinetic energy of the atoms is converted into thermal energy.
What happens when you add heat to an iron nail?
When heat is applied to an iron nail, the thermal energy causes the iron atoms to vibrate more rapidly, increasing their kinetic energy. As a result, the iron nail will expand due to the increased movement of the atoms. This expansion is a result of the increase in temperature causing the atoms to move further apart, leading to a temporary increase in the length of the nail.
Which would require a greater amount of heat water or iron?
To raise the temperature of both an equal amount, water would require more energy. In terms of the energy required to raise the temperature: iron = 0.45 joules / gram . kelvin water = 4.2 joules / gram . kelvin This is known as the specific heat capacity of a material
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.
Why was the rise in temperature obtained with zinc and copper sulfate nit much high that the rise in temperature obtained with iron and copper sulfate?
The difference in temperature rise between zinc and iron with copper sulfate is due to their differing reactivities. Iron is more reactive than zinc, so it releases more energy when reacting with copper sulfate. This higher reactivity results in a greater increase in temperature during the reaction.
