A liquefied natural gas (LNG) carrier ship is transporting fuel to a regasification terminal.

a.

Write down the equation which links density (ρ\rhoρ), mass (mmm) and volume (VVV).

[1]
b.

The ship’s cargo tanks store 180,000 m3180,000\text{ m}^3180,000 m3 of LNG. The density of the LNG is 460 kg/m3460\text{ kg/m}^3460 kg/m3. Calculate the mass of LNG transported by the ship. Give your answer in standard form.

c.

Write down the equation which links energy transferred (EEE), power (PPP) and time (ttt).

[1]
d.

The terminal’s regasification vaporizers require a continuous heating power input of 3.5×108 W3.5 \times 10^8\text{ W}3.5×108 W for 14 hours14\text{ hours}14 hours to process a portion of the cargo. Calculate the total energy transferred to the vaporizers during this period. Give your answer in standard form.
