115 J

150 J

250 J

300 J

Respuesta :

the answer is 150 J , your welcome

Answer:

[tex]Q = 150 J[/tex]

Explanation:

Heat required to raise the temperature of the object is given as

[tex]Q = m s \Delta T[/tex]

here we know that

m = mass of the object

m = 25 grams

s = specific heat capacity of the object

[tex]s = 0.39 J/g ^oC[/tex]

[tex]\Delta T[/tex] = temperature change

[tex]\Delta T = 15^o C[/tex]

now we know that

[tex]Q = 25 \times 0.39 \times 15[/tex]

[tex]Q = 150 J[/tex]
