The element that would melt first is germanium

From the question,

We are to determine the element that would melt first.

The element that would first melt is the element with the lower melting point.

From the question,

The melting point of element  germanium = 1210 K

and

The melting point of element gold = 1064  °C

First, we will convert the melting points to same units of temperature

Convert 1064  °C to Kelvin, K

Using the formula

K = °C + 273

∴ 1064  °C to Kelvin is

K = 1064 + 273

K = 1337

∴ 1064  °C = 1337 K

This means

The melting point of element gold = 1337 K

Now comparing the melting point of gold (1337 K) to the melting point of germanium (1210 K),

We can observe that the melting point of element germanium is lower.

Therefore, element germanium would melt first.

Hence, the element that would melt first is germanium

Explanation:

First, get both values into the same units

To covert from Kelvin to degrees C, subtract 273.15

1210 - 273.15 =936.85

Melting point of germanium=936.85 degrees C

Melting point of gold= 1064 degrees C

Therefore germanium would melt first because it has the lower melting point.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
