Answer: Ice is melting due to the transfer of thermal energy from Jan's hand to ice.

Explanation: The melting of ice is a physical change and is happening when the thermal energy from Jan's hand is transferred to ice. Due to this energy transfer, the particles of ice starts to move faster and hence, making the ice melt.

In this, the physical state of ice is changing from solid to liquid state.

H_2O(s)\rightleftharpoons H_2O(l)

Answer: Option (b) is the correct answer.

Explanation:

The energy of an atom or substance because of the motion of its particles is known as thermal energy.

So, when Jan is holding an ice cube, then due to the transfer of thermal energy from Jan's hand the ice, molecules of ice will start to move rapidly and thus, ice will start to melt.

That is, solid state of water (ice) will change into liquid state.

Thus, we can conclude that when Jan is holding an ice cube then ice melts because thermal energy from Jan’s hand is transferred to the ice.

Why wouldn't the concorde travel lower
Alika [10]

Supersonic flight over land is typically forbidden to minimize disruption to people on the ground. This meant that until it was over open water, Concorde could not operate at its maximum Mach 2 capability.

<h3>What is Concorde?</h3>
  • The Concorde is a tailless aircraft with a drooping nose, an oval delta wing, and a narrow fuselage that allows for seating for 92 to 128 passengers.
  • It's improbable that Concorde will ever fly for an airline again in a commercial capacity. The economics of reactivating Concorde and incorporating it into the fleet of a contemporary airline would be challenging to justify, even if the technical and regulatory concerns could be handled.
  • Supersonic flight over land is usually not allowed to minimize the impact on people on the ground. This meant that Concorde could not operate at its maximum Mach 2 speed until it was over an open body of water.

Answer;

K+ and NO3- ions

Explanation;

The main ions remaining are K+ and NO3- ions after pbi2 precipitation is complete.

However; There will always be tiny amounts of Pb2+ and I- ions, but most of them are in the solid precipitate.
