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
Answer:
According to mass and volume, block density is 2 g/ml
Explanation:
Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.
In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.
The formula used to calculate the density is
ρ = 
Therefore, according to the mass and density of the block
ρ =
= 2g/ml
Being the density of the block equal to 2 g/ml.
