I need help on this question please ASAP

439.53 J

Step-by-step explanation:

Step 1:

Here the Liquid given is 15 L = 15 kg (1 L =1 kg)

Heat required is from 28°C to 35°C

Step 2:

The heat  required is given by

Where , Q = Heat required

m = Mass

C = 4.186 J  / g ° C

T₂ = 35° C

T₁ = 28° C

 Q =

Q= 439.53 J

438.9 kJ

Step-by-step explanation:

You take the total mass which is 15000g.

You take the specific heat capacity of water. 4.18J

You take the Celsius required to increase. 35-28 = 7

15000*4.18*7 = 438900 J ---> 438.9 kJ

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
