A girl during a hike has a bottle of mineral water in her haversack. The bottle has 2 litres of water in it (2ltr. weigh 2kg). The water gets heated by the sun by 5 °C. How much heat has the water absorbed from the sun?

Respuesta :

Answer:

Q = 41800[J]

Explanation:

These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.

[tex]Q=m*C_{p}*DT[/tex]

where:

Q = Heat absorbed [J]

m = mass = 2 [kg]

DT = temperature change = 5 [°C]

Cp = specific heat of the water = 4180 [J/kg*°C]

[tex]Q=2*4180*5\\Q=41800[J][/tex]

Units of energy (Joules) [J]
