The answer will depend on the thermal capacity or heat capacity of the metal.
To raise the temperature of one cc of water requires i calorie of heat . you did not specify the volume.
The specific heat of air at 0 degrees Celsius is 1.01 Joules per gram or J/g. The specific heat of a substance is defined as the quantity of heat per unit mass needed to raise its temperature by one degree Celsius.
q (amt of heat) = mass * specific heat * temp. differenceThe specific heat of water is 1.00 cal/goC & the temperature difference is 70-30 = 40oCq = (105 grams)*(1.00 cal/goC)*(40oC)= 4,200 calories
In terms of hot to touch, yes, very high.In terms of the heat it takes to melt a metal, no, it is not very high
Use the equation for specific heat: energy = mass x (temperature difference) x (specific heat). Replace the numbers you know, and solve for mass. Since it seems that the specific heat is specified per gram, you'll initially get the mass per gram. Converting that to kilograms is quite easy.
yes
The amount of heat a substance can hold.
The specific heat is the necessary energy to raise the temperature of a mass unit (gram, kilogram, mole) of a substance with one kelvin.
The answer is 53,683 kJ.
Removing heat from the air will lower its temperature.
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
This is the necessary energy to raise the temperature of 1 gram with 1 kelvin.
The amount of heat necessary to raise 1 gram of a substance by 1 degree Celsius is known as?
If the metal's temperature has equilibriated with the water, than the temperature of the system (water and metal) will be the same.
Mass, heat capacity, the desired raise in temperature.
The higher the substance's specific heat capacity, the more heat energy is needed to raise it's temperature.
since metal is a good conductor of heat, it absorbs the heat and the spoon increases the temperature
