Copper would heat up quicker than gold or water due to its lower specific heat capacity. Specific heat capacity measures how much heat energy is required to raise the temperature of a substance. Copper has a specific heat capacity of approximately 0.385 J/g°C, while gold is about 0.129 J/g°C, and water is much higher at around 4.18 J/g°C. Therefore, for the same amount of heat energy applied, copper would reach a higher temperature more quickly than gold or water.
What else can I help you with?
What substance would absorb the most heat energy with the least change in temperature water or copper?
Copper would absorb more heat energy with less change in temperature compared to water due to its higher specific heat capacity. This means that copper can absorb more heat per unit mass before its temperature noticeably increases, while water's temperature would rise more easily when absorbing heat.
Identify the oxidizing agent in the conversion of copper metal to copper II ion?
The oxidizing agent in the conversion of copper metal to copper II ion is the other half of the redox reaction. In this case, it would be the substance that gains electrons, which is the oxidizing agent. In this reaction, the oxidizing agent would be whatever substance oxidizes the copper metal (loses electrons) to form copper II ion. This is typically noted as the substance that has "reduced" the other reactant.
If 1 liter of substance weighed 1 kilogram what would the substance be?
A substance with approximately the same density as water.
What would happen if copper sulfate evaporated?
Copper sulfate would crystalize as blue crystals, water would evaporate. To get the copper sulfate itself to evaporate you would need to heat it, melting the dry crystals then vaporizing them.
Is elemental copper a pure substance?
Yes, elemental copper is considered a pure substance because it consists entirely of copper atoms and does not contain any other elements or compounds. In its pure form, it has a consistent composition and specific properties, such as conductivity and malleability. However, copper can be found in various alloys or compounds, which would not be classified as pure substances.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
Is copper wire a pure substance?
No. Copper used in wiring would not qualify as laboratory-grade (pure). It would be far too expensive to manufacture and would not improve the conductivity enough to make a difference. Some copper wire is even plated. Laboratory-grade (pure) copper is a single substance, the element copper.
Would a copper plated object be considered a pure substance why or why not?
No because the object would consist of at least two substances, the substance in the original object and the copper in the plating.
Is copper wire a substance?
Copper used in wiring would not qualify as laboratory-grade (pure). It would be too expensive to manufacture.
What would freeze quicker tap water or salt water?
Tap water.
Why would you get a green reaction when shocking your pool with Burnout 35?
You have existing copper in your water. It can either be from well water, poor water balance causing your heater to corrode or too much of a copper algaecide. The Burnout 35, or any shock for that matter, would react and cause the water to turn green. Adding an Alkalinity increaser would also have the same affect on the copper in your pool. Take the water to be tested by a pool professional to see what the level is, then use a sequestering agent, like Pool Magnet, to put the copper back in solution and help remove it quicker with Sparkle Up added to your filter.
What would happen if cars would use water instead of gas?
we would run out of water quicker

What if a Substance A is added to water substance A does not dissolve what term can be to describe the relationship between substance A and water?
A chemist, in describing all the properties of "Substance A" would note that "Substance A is insoluble in water".
Why would water evaporate quicker if it was darker?
The absorption of heat is higher.
The density of water is equal to 1.0gcm3. a substance with density equal to cm would be what in water?
If a substance has a density of 1.0 g/cm3, it would have the same density as water. This means that the substance would neither sink nor float in water, as it would be neutrally buoyant.
