Due to the low specific heat capacity of water the temperature of water changes much more quickly than the temperature of
Sholpan [36]

This statement is <u>TRUE.</u>

Explanation:

Due to the high heat capacity of water, it takes much more energy to have a gram of water raised by one degree compared to one gram of land. This is why during a hot day, the ground gets hotter faster than the adjacent oceans or adjacent lakes. It also takes water to lose the same amount of energy to have its temperatures drop by one degree as compared to land. During the night, therefore, this is why adjacent water bodies remain relatively warmer than land.

Calculate the volume in (L) of 1.13x10^5 grams of liquid sodium which has a density of 0.929g/cm3
Yuki888 [10]

The volume of the liquid sodium is 121.64 L

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

With the above formula, we can obtain the volume of the liquid. Details below

<h3>How to determine the volume of the sodium liquid</h3>
  • Mass of liquid = 1.13×10⁵ g
  • Density of liquid = 0.929 g/cm³
  • Volume of liquid =?

Density = mass / volume

Thus,

Volume = mass / density

Volume of liquid = 1.13×10⁵ / 0.929

Volume of liquid = 121636.17 cm³

Divide by 1000 to express in liter

Volume of liquid = 121636.17 / 1000

Volume of liquid = 121.64 L

Why does silver melt ice?
Artist 52 [7]

Answer:

placing a real silver item on ice will cause the ice to melt a bit quicker. However, that’s not because of any properties in the silver itself; rather, it’s because heat melts ice , and silver is one of the best conductors of heat, according to Tom Chandler, a Metallurgical Engineer who specializes in heat treatable high-temperature copper alloys.
