Question

Gallium is a metal that has a melting point of 30°C. What change of state occurs if you hold it in a warm hand?

Answer 1

When you hold gallium in a warm hand, it will melt and change from a solid to a liquid state.

Step-by-step explanation:

When you hold gallium in a warm hand, it will undergo a change of state from solid to liquid. This change is called melting. Gallium has a melting point of 30°C, which means that at temperatures higher than this, it will transition from a solid state to a liquid state.

The melting point of gallium is relatively low compared to other metals. This is because gallium has weak metallic bonding, which causes the atoms to move more easily and transition into a liquid state at lower temperatures.

It's important to note that the heat from your hand raises the temperature of the gallium until it reaches its melting point, and then the heat is used to break the bonds between the gallium atoms, resulting in the change of state.

Answer 2

Answer : It will turn to liquid state

Explanation :

Gallium is a chemical element it is almost similar to aluminum it's atomic number is 31. This element is different from other elements it has low melting point 29.76 °C If any human touches it will warm hand it will melt because the temperature of hand is greater than the melting point of the gallium, so it turns from solid to liquid state.
