It shows the natrual proggresion of a story and helps blend the narrtive together.
Answer:
Cp = 0.237 J.g⁻¹.°C⁻¹
Explanation:
Amount of energy required by known amount of a substance to raise its temperature by one degree is called specific heat capacity.
The equation used for this problem is as follow,
Q = m Cp ΔT ----- (1)
Where;
Q = Heat = 640 J
m = mass = 125 g
Cp = Specific Heat Capacity = <u>??</u>
ΔT = Change in Temperature = 43.6 °C - 22 °C = 21.6 °C
Solving eq. 1 for Cp,
Cp = Q / m ΔT
Putting values,
Cp = 640 J / (125 g × 21.6 °C)
Cp = 0.237 J.g⁻¹.°C⁻¹
I could lift 3.06 x 10⁵ m high
<h3>Further explanation
</h3>
Energy is the ability to do work. Energy can change from one energy to another
Potential energy is the energy that an object has because of its position
The potential energy can be formulated:
Ep = m. g. h
E = potential energy of an object, joule
m = object mass, kg
g = gravity acceleration, m / s²
h = height of an object, m
energy of coal = 3.10⁶ J
mass = 1 kg
g = 9.8 m/s²
The molecular formula of a compound having the empirical formula C9H17O is calculated as below
(C9H17O)n =847.56
{(12 x9 + 1 x17 + 1 x16)}n= 847.56
147 n = 847.56
divide bot
h side by 147
n= 6
(C9H17O)6 therefore the molecular formula = C54H102O6
