(1) - (a) heat, the amount of energy transferred between two objects is considered heat.
(2) -(b) specific heat of soil is higher..due to this it takes more time to heat

When two objects are in thermal contact heat energy is transferred from the hot to the cold object until the temperature of both becomes equal (i.e., the objects are in thermal equilibrium). Suppose you pour 20-gram milk at 200C into a cup of 80-gram tea at 920C. Assume the specific heat of tea is 4.2 J/gram.0K and that of milk is 3.9 J/gram.0K Assuming no heat is lost into the surrounding air what is the temperature of the tea and...
object A has higher specific heat than object B. that means a- has more mass than B b- A has higher boiling point than B c-A takes more heat energy than B d- A is liquid and b is solid
Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...
Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change q=m⋅Cs⋅ΔT where Cs is specific heat and m is mass. Heat can also be transferred at a constant temperature when there is a change in state. For a process that involves a phase change q=n⋅ΔH where, n is the number of moles and ΔH is the enthalpy of fusion, vaporization, or sublimation. The following table provides the specific heat and enthalpy...
When two objects with different temperatures are placed in contact, the amount of heat transferred into the colder object is proportional to i. The change in the object's temperature ii. The mass of the object iii. The specific heat of the object i. and ii. i. and iii. ii. and iïi. i., ii., and iii.
5. Because of the high specific heat capacity of water compared to that of soil, a large lake takes longer to heat in the summer than an equivalent area of land. This effect moderates the temperature along the lakeside. But how does the cooler lake keep lakeside communities cooler, i.e. what is the mechanism of energy transfer? (0.5 mark)
Consider the following statements. A. Heat flows from an object in liquid state to an object in solid state; B. Heat flows from an object with higher thermal energy to one with lower thermal energy; C. Heat flows from an object at higher temperature to an object at lower temperature. Which statements are true? 1. All are true. 2. C only 3. A and B only 4. A only 5. B and C only 6. None is true. 7. B...
Two objects, with different sizes, masses, and temperatures, are placed in thermal contact. Energy travels (a) from the larger object to the smaller object (b) from the object with more mass to the one with less (c) from the object at higher temperature to the object at lower temperature.
Suppose you transfer a certain amount of heat energy to a known amount of a liquid in a perfectly insulated cup and the temperature changes. Then, you decide to alter the experiment in several different ways. Match the alterations listed below with the best description of the total change in temperature compared to that measured in the original experiment (before the alteration): - A Transfer more heat energy A. The total change in temperature will be smaller. - A Heat...
