Answer:

B

Explanation:

Ocean currents has to do with rising of cold salty water to replace the warm salty water at the top of the ocean. A convection current is thus set up continually. Convection refers to the movement of particles due to a temperature gradient between layers of fluid. Convection is one of the modes of heat transfer. Energy from the sun warm up the surface of the ocean by radiation. Hence radiation and convection are two ways by which energy from the sun affect ocean currents.

When 28 grams of a metal are heated from 14.4°C to 150°C it takes 23,200). What is the specific heat of the metal?
suter [353]

Answer:

6.11 J/g°C

Explanation:

We need to use the heat equation: q = mCΔT, where q is the amount of heat required in Joules, m is the mass in grams, C is the heat capacity, and ΔT is the change in temperature.

Here, we know q = 23,200 Joules, m = 28 grams, and the ΔT is just the difference of the temperatures: 150 - 14.4 = 135.6°C. Substitute these values to find C:

q = mCΔT

23,200 = 28 * C * 135.6

C = 6.11

Thus, the specific heat is 6.11 J/g°C.
