the amount of warmth that is compelled to progressive 1 g that the sample by 1°C (Kelvin) at a continuous pressure
The details heat that water is 4.18 J/(g°C) and also that of timber is 1.97 J/(g*°C). I beg your pardon statement is correct?
What would certainly be the greatest distinction in making use of an open ceramic coffee mug rather than one insulated mug through a lid as a calorimeter?
Which statement best describes why particular heat volume is often more useful than warmth capacity because that scientists once comparing 2 materials?
It offers the massive and certain heat of water along with a thermometer to measure up the gain or loss of energy when a problem is added.
The heat capacity of a sample need to be divided through which quantity to find the details heat capacity?
Heat that flows by conduction is the move of heat energy in between substances in contact. What must happen for this to happen?
