Answer:

The answer to your question is: 28°C

Explanation:

Data

mass = 10 g

T1 = 23°C

T2 = ?

Q = 209 joules

Formula

Q = mC(T2 - T1)

T2 = Q/mC + T1

T2 = 209/(10 x 4.182) + 23

T2 = 4.99 + 23

T2 = 27.99 ≈ 28°C

A serving of Frosted Flakes cereal contains 235,000 J of energy. Calculate the change in temperature (ΔT) that would occur if th
timama [110]

The change in temperature (ΔT) : 56.14 ° C

<h3>Further explanation</h3>

Given

Cereal energy = 235,000 J

mass of water = 1000 g

Required

the change in temperature (ΔT)

Solution

Heat can be formulated :

Q = m . c . ΔT

c = specific heat for water =  4.186 J / gram ° C

235000 = 1000 . 4.186 . ΔT

\tt \Delta T=\dfrac{235000}{1000\times 4.186}=56.14^oC
