The amount of heat (in calories) needed to raise the temperature is 324.885 calories
<h3>How to determine the temperature change </h3>
We'll begin by obtaining the temperature change. This can be obtained as followed:
- Initial temperature (T₁) = 14 °C
- Final temperature (T₂) = 25 °C
- Change in temperature (ΔT) = ?
ΔT = T₂ - T₁
ΔT = 25 - 14
ΔT = 11 °C
<h3>How to determine the heat (in Calories)</h3>
The amount of heat needed to raise the temperature can bee obtaimedals follow:
- Mass (M) = 33 g
- Change in temperature (ΔT) = 11 °C
- Specific heat capacity (C) of diethyl ether = 0.895 cal/g°C
- Heat (Q) =?
Q = MCΔT
Q = 33 × 0.895 × 11
Q = 324.885 calories
Thus, the amount of heat needed is 324.885 calories

1. Answer is d. all of the above.
Climate can be defined as the data collection of weather conditions of a long period of time in a certain area. The weather conditions that affect to the climate are temperature, precipitation, atmospheric pressure, wind and so on. Any changes in weather can change the global climate.
2. Answer is c. ozone.
Trees release oxygen and water vapor into the atmosphere but not ozone. The oxygen gas is released by trees as the by-product of photosynthesis. This is the natural way of production of oxygen gas. Water vapor can be released due to the transpiration of trees.
The first scientist to show that atoms emit tiny negative particles was J. J. Thomson.
Your answer is D! Sublimation is a physical process in which solid states is converted to gaseous state. The volume of the substance increases and in this case, the increment in volume is the maximum.
