Answer:
0.583 kilojoules
Explanation:
The amount of heat required to pop a single kernel can be calculated using the formula as follows:
Q = m × c × ∆T
Where;
Q = amount of heat (J)
m = mass of water (g)
c = specific heat capacity of water (4.184 J/g°C)
∆T = change in temperature
From the given information, m = 0.905 g, initial temperature (room temperature) = 21°C , final temperature = 175°C, Q = ?
Q = m × c × ∆T
Q = 0.905 × 4.184 × (175°C - 21°C)
Q = 3.786 × 154
Q = 583.044 Joules
In kilojoules i.e. we divide by 1000, the amount of heat is:
= 583.04/1000
= 0.583 kilojoules
Answer:
Time is something I constantly run out of-
Answer:
<h2>120 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 8 × 15
We have the final answer as
<h3>120 N</h3>
Hope this helps you
Answer:
Cookies definitely obeys the law of conservation.`
Explanation:
As, When Maria mixes up the ingredients, Water was also one among them
And, Initially When she was measuring the weight of Ingredients, Weight of Water was coming,
But,
When She baked the cookies , water from the cookies got evaporated , and thus weight coming was decreased finally.
Considering Cookies and Environment Whole as a system You can clearly say that they obeys Law of conservation of mass , As Water is present in Environment for now.
