<h2>If the object is moving then it has kinetic energy</h2>
Answer:
14 L
Explanation:
The ice water will have to be warmed up to 37 oC
Quantity of heat gain the ice water = mcΔT
where m is the mass of water, c is the specific heat capacity of water
heat gain = heat loss
heat expected the body to lose = 520kcal = 520 × 4184 J ( 1 kcal is 4184 J)
520 × 4184 = 4200 × m × 37
m = (520 × 4184) / ( 4200 × 37) where specific heat capacity of water is 4200J/KG.K
but density = m/V where V is volume in m³
m = ρ×V
replace m with the above formula
ρV = (520 × 4184) / ( 4200 × 37) and density of water is 1000kg/m³
V = (520 × 4184) / (4200 × 37 × 1000) = 0.014 m³ = 0.014 × 1000 ( 1m³ = 1000L) = 14 L
exercise will be better as it is not quite possible to drink this (14 L) volume of ice cold water.
Your equation is:
An equation is balanced only if there are the same number of atoms of each element on both sides of the arrow - aka same number of atoms of each element in both reactants (left of the arrow) and products (right of the arrow).
It'll be easiest to tackle this by counting up the number of atoms of each element on the left and on the right and comparing those numbers. If there is a number in front of the entire compound, that means that number applies to all elements in the compound. If the number is a subscript (little number to the right of the element), that means that number only applies to the element that the subscript is attached to:
1) On the left, you have:
2) On the right, you have:
You can see that the number of oxygen and hydrogen atoms aren't equal on both the left (reactants) and the right (products), so the equation is unbalanced.
Your final answer is "T<span>he equation is
unbalanced because the number of hydrogen atoms and
oxygen is
not equal in the reactants and in the products."</span>
Speed is not a measure of how fast something moves <u>in</u> a specific direction. It is just the average speed per time unit without a direction. A direction is for velocity. The answer is false.
I hope this helps. :)
