Based on the thermodynamic properties provided for water, determine the energy change when the temperature of 1.25 kg of water decreased from 113 °c to 55.0 °c.

Energy change = -303050 J

Explanation:

the heat energy Q is given by the formula

Q= m C ΔT

m= mass of water=1.25 Kg

C= specific heat of water= 4180 J/Kg °C

ΔT= change in temperature =55-113= -58°C

Q= 1.25 (4180) (-58)

Q=-303050 J

Negative sign shows that the energy is released or lost.

kinetic

i'm so sorry if this is wrong i'm only in 6th grade xd

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
