1) we find out the volume of the water.
Remember: 1 ml=1 cm³
Volume of the water=number of cups x volume of one cup.
Volume of the water=2.5(240 ml)=600 ml=600 cm³
Density=mass/volume ⇒ mass=density x volume
2) we calculate the water mass of 600 cm³ of water.
mass=density x volume
mass=(1 g/cm³)(600 cm³)=600 g.
Answer: the mass of 2.5 cupas of water is 600 g.
Endo is more in reactants and exo is more in products because in exothermic reactions heat is released
Absolute dating is finding the exact date of an artifact such as a fossil using a technique such as radioactive dating, etc.
Answer:
when a substance is heated it gains thermal energy. Therefore its particles move faster and its temperature rises. when a substance is cool it loses thermal energy which causes its particles to move more slowly and its temperature to drop

Answer:</h3>
79.8 ml
<h3>
Explanation:</h3>
Boyle's law describes the relationship between pressure and volume when the temperature is constant. For this question, I will be rounding to significant figures.
Boyle's Formula
When describing the relationship between pressure and volume, the formula 
. In this formula, 
is the initial pressure and volume. On the other side, 
is final pressure and volume. So, to find a missing variable you must plug in the values you are given.
Final Volume
Remember when solving this question to remain constant in your units. When we plug in the values we know we are given:
Now, we can multiply the left side
Finally, we can divide by 385 to isolate the final volume
This gives the final volume of 79.8mL.
