Answer:
The answers to your questions are given below.
Explanation:
Data obtained from the question include:
Mass (M) = 420.0 g
Temperature change (ΔT) = 43.8 °C
Specific heat capacity (C) = 3.52 J/g °C
Heat needed (Q) =...?
The heat needed for the temperature change can be obtained by using the following formula:
Q = MCΔT
Where:
Q is the heat needed measured in joule (J).
M is the mass of substance measured in grams (g)
C is the specific heat capacity of the substance with unit J/g °C.
ΔT is the temperature change measured in degree celsius (°C).
Thus, we can calculate the heat needed to change the temperature as follow:
Q = MCΔT
Q = 420 x 3.52 x 43.8
Q = 64753.92 J
Therefore, the heat needed to cause the temperature change is 64753.92 J
Answer : It will take 366 minutes to fill 1.00 gallon bucket.
Explanation :
We have been given the drip rate which is 41 drops/min
Let us use this as a conversion factor to ind out the minutes taken to fill 1 gal bucket. We will arrange this conversion factor in such way that , "drops" would get cancelled.
They have also given us that 1 gallon bucket contains 15000 drops.
The equation can be set up as follows.
It will take 366 minutes to fill 1.00 gal bucket.
