Lustrous
High melting point
Malleable
Ductility
The question is based on the Thermodynamic principle of Specific Heat Capacity. Now, Specific Heat Capacity refers to the amount of heat needed per unit mass t raise the temperature by one degree Celsius
The formula that can be used to find the answer is the following:
Q = C · m · ΔT ( where Q is the heat added/required; C is the specific heat capacity [4.186 joule/gram °C]; ΔT is the change in temperature)
Based on the question, what needs to be found is Q, and what is known is that C = 4.186 J/g °C; m = 15 g; ΔT = 10 °C
so, Q = C · m · ΔT
Q = (4.186 J/g °C) (15 g) (10 °C)
Q = 627.9 J
Thus, the number of <span>joules required to raise the temperature of 15.0 grams of water by 10 degrees Celsius is 627.9 J</span>
Answer:
I think it is the second one
Explanation:
Because what the cold water did to the table salt, is that it separated its molecules dissolving the salt.
even though the rock salt was in hot water it was a bigger particle. But the big difference was only because the water temperature ️.
6,200,0 is the answer to that
Answer:
Carbon Dioxide?
Explanation:
When we take a breath, we pull air into our lungs that contains mostly nitrogen and oxygen. When we exhale, we breathe out mostly carbon dioxide.
