Answer:
true
Explanation:
as temperature decreases, medium particles move slower. so it would take longer for energy to transfer into sound waves.
Given:
128g sample of titanium
2808J of heat energy
specific heat of titanium is 0.523 J/ g °C.
Required:
Change in temperature
Solution:
This can be solved
through the equation H = mCpT
where H is the heat, m is the mass, Cp is the specific heat and T is the change in temperature.
Plugging in the
values into the equation
H = mCpT
2808J = (128g) (0.523
J /g °C) T
T
= 41.9 °C
A polar molecule is when the arrangement of the atoms in molecules are unequal, so one end of the molecule has a positive charge, and the other end has a negative charge.
