What is missing from the temperature and volume graph shown at right?

Answer: Three things are missing:

i) Graph title.

ii) Label for the vertical axis.

iii) The scale and the units for the horizontal axis.

Justification:

1) Find the graph in the image attached.

2) What does the graph represent? You cannot tell because it does not show the tittle.

Since you are told in the statement that it is a temperature and volume graph, the appropiate title would be:

Temperature vs. Volume.

3) The vertical axis also must be properly labeled, including the units.

A good label for the vertical axis of this graph might be: Volume (cm³). It migh also be liters, gallons, or other volume unit.

4) Although the horizontal axis is labeled, it does not indicate the units and the scale. So, you know neither if the temperature shown is celsius, (°C), farenheti (°F), kelvin (K), or rankine (R) (those are the four major scales of temperature), nor how much each division represent (1, 5, 10, 10, 50, 100?)

Hello Olivia!!!

Q.) Describe at least two geological events that can occur at a divergent boundary.

A.)Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.

Hope this can help!!!

Suppose you are working in a chemistry lab and trying to make a solution of a substance called Sodium Chloride (which is a solid

Alenkasestr [34]

Answer:

a weighing balance, a measuring cylinder, a spatula, a beaker/flask, and a stirrer

Explanation:

The lab apparatus that would be needed to prepare a solution of sodium chloride would be a weighing balance, a measuring cylinder, a spatula, a beaker/flask, and a stirrer.

The weighing balance would be used to weigh out the required amount of sodium chloride. The beaker or flask would be placed on the weighing balance and its weight zeroed. The spatula would then be sued to take out the sodium chloride from its container into the beaker till the required amount is reached. The measuring cylinder would then be used to measure out the required volume of water which would be added to the salt in the beaker. The stirrer would then be used to stir the mixture in order for the salt to dissolve.

60 grams of ice will require _____ calories to raise the temperature 1°C.

guajiro [1.7K]

Answer:

60 grams of ice will require 30.26 calories to raise the temperature 1°C.

Explanation:

The amount of heat (Q) to raise the temperature of 60.0 g of ice by 1°C can be calculated from:

Q = m.c.ΔT,

where, Q is the amount of heat released or absorbed by the system.

m is the mass of the ice (m = 60.0 g).

c is the specific heat capacity of ice (c = 2.108 J/g.°C).

ΔT is the temperature difference (ΔT = 1.0 °C).

∴ Q = m.c.ΔT = (60.0 g)(2.108 J/g.°C)(1.0 °C) = 126.48 J.

It is known that 1.0 cal = 4.18 J.

∴ Q = (126.48 J)(1.0 cal / 4.18 J) = 30.26 cal.
