Answer : The specific heat of substance is
Explanation :
Formula used :
or,
where,
Q = heat needed = 4.90 kJ = 4900 J
m = mass of sample = 894.0 g
c = specific heat of substance = ?
= initial temperature =
= final temperature =
Now put all the given value in the above formula, we get:
Therefore, the specific heat of substance is
Answer:
C.) evaporation
Explanation:
When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation.
I hope this helps! :)
Different forms of matter have different melting/boiling points. For example, at 100 degrees Celsius, H2O (water) will turn from lliquid to gas. But NaOH (table salt) doesn't even go from solid to liquid until some 800 degrees Celsius. So, in order to figure out which state matter is at 35 Celsius, you'd have to be more specific about what kind of matter...
Answer:
I think 0kg because they are flying.
Answer:
The outermost shell holds the so called valence electrons, therefore we have 8 electrons in that shell...
2s have 2 electrons and 2p hold 6 electrons 6+2=8
