Thermal convection
Explanation:
When ice cubes are placed in water, ice cubes start melting. This is because water transfers its heat to ice cubes until the temperature becomes equal and the process is called "thermal Convection".
Thermal convection is the mode of transfer of heat energy that will occur when ice cubes will be added to the hot water and at the end of the experiment when both are at the same temperature, no ice cube will left.
Hence, the correct answer is "thermal convection".

and as it descends and more and more of it goes under, the
buoyant force on it increases during that time.
As soon as the object is completely underwater, it doesn't matter
how deep under it is, the buoyant force on it remains the same.
As an object sinks in a fluid, the buoyant force decrease.
Hope this helped.

Answer:
This expression is True
Since the Ohm's Law "states that the current )I) through a material between two points is proportional to the voltage across the two points." and i defined by this formula:
Where V represent the voltage and it's a value related to the emf and the potential
I represent the current
R represent the resistance.
And for this case we have an expression for this case relating the emf , potential, current and resistance

V = IR The relationship between electrical resistance, current, and voltage is defined by the mathematical relationship V= IR and is referred to as Ohm's law. In this equation "V" stands for voltage, measured in volts, "I" stands for current, measured in amperes, and "R" stands for resistance, measured in Ohms (Ω ).Common sources of voltage in circuits may be chemical cells (a battery is a combinations of cells) and generators. Sources of electrical resistance in circuits may include resistors, light bulb filaments, wire conductors and other electric devices. When solving Ohm's law problems you are expected to solve for any unknown variable.
Example: Determine the voltage of the circuit shown below in diagram "A".Diagram A In this circuit we are given the current from the ammeter .2A. We also can determine the resistance. Since this is a series circuit the total resistance is the sum of the resistances of L1 and L2, 70Ω . We set the problem up and solve it like this.
V=IR
V=.2A 70Ω
V= 14VThe answer is 14V

Matter can be defined as something that has mass and occupies space. They are present in the atmosphere in different phases. Thus, the correct option is C.
What is Matter?
Matter is any substance which is made up of various types of particles that occupies some physical space and has mass. According to the modern physics, there are various types of particles with each having a specific mass and size. The most common examples of these material particles are electrons, protons and neutrons.
Matter is present in different phases in the atmosphere. The three phases are solids, liquids, and gases. All of these phases show mass and occupies some space.
Therefore, the correct option is C.

To solve this we assumethat the gas inside the balloon is an ideal gas. Then, we can use the ideal gasequation which is expressed as PV = nRT. At a constant pressure and number ofmoles of the gas the ratio T/V is equal to some constant. At another set ofcondition of temperature, the constant is still the same. Calculations are asfollows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 308 K x 556 cm³ / 278 K
V2 = 616 cm³
