To determine the temperature range at which the decomposition of KClO4 is spontaneous, you would need the values for the standard Gibbs free energy change (ΔG°) and the equilibrium constant (K). By using the equation ΔG = -RTlnK and taking into account that ΔG = 0 for a reaction at equilibrium, you can rearrange to solve for the temperature range where decomposition is spontaneous.
The heat of vaporization of nitrogen is 5.56 kJ/mol at its boiling point of -195.79°C. This is the energy required to change 1 mole of liquid nitrogen at its boiling point to gas at the same temperature.
Using the specific latent heat of fusion for aluminum (397 kJ/kg), we can calculate the energy required to melt 2 kg of aluminum: Q = m * L Q = 2 kg * 397 kJ/kg Q = 794 kJ Therefore, it would require 794 kJ of energy to melt 2 kg of aluminum.
There is NO temperature at all below 0 (zero) Kelvin, because that is the ABSOLUTE zero point, absolute zero, the point at which there is an total absence of all thermal energy. Energy can be negative, the same as mass and eg. volume of matter.
A substance becomes a liquid below its freezing point. At this temperature, the solid state will melt into a liquid due to the absorption of heat energy.

The reaction is spontaneous below 554.8/0.1975 K.
The heat of vaporization of gold is 158 kJ/kg. To find the total energy required to vaporize 2 kg of gold, you can use the equation: Energy = mass * heat of vaporization. Substitute the values to get: Energy = 2 kg * 158 kJ/kg = 316 kJ. Therefore, 316 kJ of energy is required to vaporize 2 kg of gold.
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.
Well what is the baked item?
ground temperature below freezing, and air temperature slightly above freezing.

No. Hypothermia is caused when an organism's temperature drops below the temperature required for normal body functions.
When kept in the refrigerator, a temperature at or below 40° F (4° C) is required.
