Gold takes less heat energy than water to change temperature due to its lower specific heat capacity. Specific heat capacity is the amount of heat required to raise the temperature of a substance by one degree Celsius. Water has a high specific heat capacity, meaning it can absorb more heat without a significant temperature change, while gold, being a metal, has a much lower capacity, allowing it to heat up or cool down more quickly with less energy input.

How do you change LIQUID GOLD into SOLID GOLD?
To change liquid gold into solid gold, you need to cool it down to a temperature at which it solidifies. Gold melts at 1,064 degrees Celsius (1,948 degrees Fahrenheit) and re-solidifies when the temperature drops below this point. Simply allowing the liquid gold to cool naturally or using a cooling process can transform it into solid gold.
What is the color of the water if mixed with pure gold?
If pure gold is mixed with water, the resulting color would be a clear or slightly yellowish hue, as gold is a yellow metal and would impart its color to the water.
What happens to temperature as solid gold turns to a liquid?
As solid gold turns into a liquid, the temperature remains constant until all the solid has melted. This is known as the melting point of gold. Once all the solid has melted, the temperature will begin to rise again as heat is absorbed by the liquid gold.
A sheet of gold weighing 10.0g and at a temperature of 18.0 is placed flat on a sheet of iron weighing 20.0g and at a temperature of 55.6 C. Specfific heats of gold and iron are 0.129 and .444 respec?
To determine the final temperature when the two metals reach thermal equilibrium, you can use the principle of conservation of energy. The heat lost by the iron as it cools (Q = mcΔT) equals the heat gained by the gold as it warms up (Q = mcΔT), where m is the mass of the metal, c is the specific heat, and ΔT is the change in temperature. Equating these two and solving for the final temperature will give you the answer.
What happens when removing Thermal Energy from gold?
Removing thermal energy (or, to be accurate INTERNAL energy since in thermodynamics thermal energy is a deprecated term) will usually cause it to get cooler. If it is near a phase boundary it may, instead cause some of it to change phase (solidify from liquid for example). Since electrical resistance is dependent on temperature, it will also lower the electrical resistance.
Does 1 kilogram of water have the same amount of thermal energy as 2 kilogram of water?
No they wouldn't, this refers to specific heat capacities. Generally, gold has a lower heat capacities than of water, thus it takes less energy to change the temperature of gold than it does to change the temperature of water. So if you add the same amount of heat to both systems of water and gold, the gold will be hotter than the water.
When heated water changes temperature very slowly but gold changes temperature very quickly this is because water has a higher?
Heat capacity, it takes more energy to raise the temperature of water 1o than it does gold 1o. That's why if you apply the same amount of heat to gold and water the gold will heat up faster (i.e., change temperature quicker).
Why it takes more energy to raise the temperature of water than it does gold?
Water has a higher specific heat capacity than gold, meaning it requires more energy to raise its temperature. This is because water molecules can hold more heat energy due to their intermolecular structure compared to gold. As a result, more energy is needed to increase the kinetic energy of water molecules and raise the temperature of water.
Which of these substances requires the least amount of energy to raise its temperature 'wood' 'water' 'gold' or 'aluminum'?
Aluminum requires the least amount of energy to raise its temperature compared to wood, water, and gold. This is because aluminum has a lower specific heat capacity, meaning it can heat up more quickly with less energy input.
What has more internal energy 25 kg of water or 25 kg of gold at thermal equilibrium?
The 25 kg of gold has more internal energy than 25 kg of water at thermal equilibrium because gold has a higher specific heat capacity and a higher melting point than water. This means that it takes more energy to raise the temperature of gold compared to water, resulting in gold having more internal energy even at the same temperature.
Which has more thermal energy gold or aluminum?
Aluminum has more thermal energy compared to gold because aluminum has a higher specific heat capacity, meaning it can absorb and retain more heat energy for a given temperature change.
If gold does react to water is it a chemical or physical change?
gold has no reaction in water, or acid. if there is no reaction that means no chemical reaction. the gold gets wet, or changes temperature in the water, that might be considered a physical change. gold is remarkably unreactive as far as metals go.
How many calories will it take to raise the temperature of a 36 g gold chain from 20 and degC to 125 and degC?
To calculate the energy required to raise the temperature, you can use the formula: energy = mass x specific heat capacity x temperature change. The specific heat capacity of gold is 0.129 J/g°C. Plugging in the values for mass, specific heat capacity, and temperature change, the energy required would be approximately 364.86 Joules. To convert Joules to calories, divide by 4.184 to get approximately 87.2 calories needed to raise the temperature of the gold chain.
What substance below requires the most energy to raise its temperature by 7 degrees C?
water
How much energy is required to melt 1.5 kg gold?
The specific heat of gold is 0.129 J/g°C, and its melting point is 1064°C. The energy required to melt 1.5 kg of gold can be calculated using the formula: Energy = mass * specific heat * temperature change. So, the energy required would be approximately 2.3 x 10^6 Joules.
Which substance is a solid at room temperature water nitrogen mercury or gold?
Gold is a solid at room temperature. It wouldn't make a good wedding ring otherwise.
What is the effect of temperature on the behavior of goldfish?
It is a known fact that fish can change its temperature on its own. It implies that change in temperature doesn't change the behavior of the fish. This is true with gold fish also. A gold fish tends to move more randomly if more light falls on it.
