How much heat is required to melt 2 kg of gold?
The specific heat capacity of gold is 0.129 J/g°C. The heat required to melt 2 kg of gold can be calculated by using the formula Q = m * c * ΔT, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Assuming gold melts at 1064°C and starting from room temperature (20°C), the total heat required to melt 2 kg of gold is approximately 3.6 x 10^5 Joules.
What is the reaction between HNO3 and Fe?
It depends on what temperature, depending on the temperature and concentration of the acid you will either get Iron(II) nitrate or Iron(III) nitrate, along with nitric oxide or nitrogen dioxide.
What is the conversion of mmilligrams per killograms to milligrams?
To convert milligrams per kilogram (mg/kg) to milligrams (mg), you would multiply the value in mg/kg by the weight in kilograms. For example, if you have a value of 5 mg/kg and a weight of 10 kg, the calculation would be 5 mg/kg x 10 kg = 50 mg.
How many milligrams of ammonium nitrate are equivalent to 7.42 x 10 -5 kg of ammonium nitrate?
This is to be calculated with: 1 kg = 1*10+3 gram (g) = 1*10+6 milligram (mg)So 7.42*10-5 kg = [7.42*10-5(kg)] * [1*10+6(mg) / 1(kg)] = 7.42*10-5+6(kg.mg.kg-1) = 74.2 mg(Note: This is the same for the same mass of all compouds, not exclusively valid for ammonium nitrate

How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C Use the table below and this equation Q mcT. Substance Specific Heat Capacity Liquid water 4.186 Ice 2.11 Air 1.00?
The specific heat capacity of iron is about 0.45 J/g°C. To raise the temperature of 3 kg of iron by 5°C, you would use the equation Q = mcΔT, where m is the mass (3 kg), c is the specific heat capacity (0.45 J/g°C), and ΔT is the change in temperature (5°C). Therefore, the energy required would be around 6,750 Joules.
How much heat is required to melt 5 kg of ice?
The heat required to melt 5 kg of ice is 334,750 J. This is calculated using the formula Q = m * Lf, where Q is the heat energy (Joules), m is the mass of the substance (kg), and Lf is the specific latent heat of fusion for ice (334,750 J/kg).

How would a 5 kg chunk of aluminum and a 5 kg block of silver at the same temperature compare in thermal energy?
Both the 5 kg aluminum chunk and the 5 kg silver block will have the same amount of thermal energy if they are at the same temperature, as the thermal energy is directly proportional to the temperature and the mass of the object. Therefore, both objects will require the same amount of heat energy to raise their temperature by a certain amount.
How much heat is needed to raise the temperature of 5 kilograms of iron by 50 degrees given specific capacity of iron is 470 J?
The heat needed is calculated using the equation Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Plugging in the values, Q = 5 kg * 470 J/kg°C * 50°C = 117,500 J or 117.5 kJ.
If you drop a 15 kg iron bar and a 5 kg bag of cotton from a height of 50 meters which will reach the ground first?
iron bar first
Does a 5 kg chunk of aluminum and a 5 kg block of silver that are at the same temperature have the same thermal energy?
No, the thermal energy of the aluminum and silver blocks would not be the same even if they are at the same temperature. This is because different materials have different specific heat capacities, meaning they require different amounts of energy to raise their temperature by the same amount.
How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C?
1935 J
Does the snow melt at -5 degree centigrade temperature?
Yes, by adding salt and applying pressure.
How long does it take to melt cheese in the oven?
The time it takes to melt cheese in the oven can vary depending on the type of cheese and the temperature of the oven. Generally, it can take anywhere from 5 to 10 minutes for cheese to melt in the oven.
How long does an ice cube take to melt?
The time it takes for an ice cube to melt can vary depending on factors such as the temperature of its surroundings, the size of the ice cube, and the material it is made from. On average, a small ice cube in a room temperature environment may take around 5-10 minutes to melt completely.
How long does it take to melt ice in 5 degrees?
The time it takes to melt ice at 5 degrees Celsius depends on factors such as the amount of ice and the surrounding conditions. Generally, it will take a few minutes to several hours for ice to melt at this temperature.
