Answer : The specific heat of tungsten is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of tungsten = ?
= specific heat of water =
= mass of tungsten = 19.5 g
= mass of water = 78.5 g
= final temperature =
= initial temperature of tungsten =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat of tungsten is,
The law of conservation of mass says that matter cannot be created or destroyed. This means that when a chemical reaction happens, you can never create new atoms or destroy the ones that are reacting, they simply rearrange themselves into new substances.
For purposes of looking at chemical equations, this means that the equation that describes the reaction has to be "balanced". In other words, there must be the same number and same kind of atoms on the reactant side of the equation as there are on the product side to ensure that no atoms are created or lost during the reaction.
I'm pretty sure the answer is
<span>A) radon, neon, calcium </span>
0 N stopping at stop sign.
In order to <span>decrease the pressure of a gas inside a closed cubical container, you need to decrease the temperature of the container. The volume of the system is rigid so it means volume is constant. By the ideal gas law, temperature and pressure are directly related. Increasing the temperature, increases the pressure and the opposite to happens.</span>
