Answer:
I believe the answer is "b". "During the experiment, the scientist has only one element, or variable, that is changed to test the hypothesis."
Explanation:
I remember from last year but I'm not totally sure. Good luck!
Increasing order of strength needed to break bonds:
temporary dipole induced dipole interactions
Permanent dipole induced dipole interactions
Hydrogen bonding
Answer:
<h2>59.1 m</h2>
Explanation:
The height of the object can be found by using the formula
where
p is the potential energy
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
We have the final answer as
<h3>59.1 m</h3>
Hope this helps you
Answer:
It will reduce
Explanation:
The time it will take to bake the cake will reduce when the temperature is increased by an additional 20°F .
Temperature change has a considerable effect on reaction rates since temperature is directly proportional to the average kinetic energy of reacting particles.
Generally reaction rate varies as temperature directly.
Therefore, the baking time will reduce as temperature increases.
Answer:
When 22.0 g of water is heated from 17 °C to 100 °C what amount of heat absorbed?
When 22.0 g of water is heated from 17 °C to 100 °C water absorbed 7643.64 j heat.
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Given data:
Mass of water = 22.0 g
Initial temperature = 17°C
Final temperature = 100°C
Solution:
ΔT = T₂ -T₁
ΔT = 100°C - 17 °C= 83°C
Q = m.c. ΔT
Q = 22 g× 4.186 j/g °C × 83 °C
Q = 7643.64 j
It means water require more heat which is 7643.64 j to increase its temperature from 17 °C
to 100 °C
