Answer: True
Explanation:
The matter exists as solid, liquid or gas. These are called the states of matter. The change of matter from one state to another can be achieved by heating or cooling.
The solid state can be converted into liquid state by providing heat to solid. The heat will make the particles move farther, resulting into liquid state.
Similarly when liquid state is provided heat, it changes to gaseous state. The heat will make the particles move much more faster.
Thus the statement that when heat flows to an object, it can change states is True.
What is the percent composition by mass of oxygen in magnesium oxide, MgO?
Answer: 39.7 percent
Answer:
The answer to your question is: Cp = 0.129 J/g°C
Explanation:
Data
mass = 955 g of tungsten
T1 = 18°C
T2 = 100°C
Q = 10180 Joules
Cp = ?
Formula
Q = mCpΔT
Clear Cp from the equation
Cp = Q / mΔT
Substitution
Cp = 10180 / (955(100-18))
Cp = 10180 / (955(82))
Cp = 10180 / 78310
Cp = 0.129 J/g°C
